A sleeve clamp has a body with a through bore for receiving a sleeve, and a clamping element. The clamping element includes a clamping edge and may be arranged at the body so as to be movable between two positions, i.e. a neutral position and a deflected position. In the neural position, the clamping edge protrudes laterally into a lumen which is occupied by the sleeve when the sleeve is received in the through bore. In the deflected position, the clamping element may be elastically deformed and the clamping edge does not protrude into the lumen which is occupied by the sleeve when the sleeve is received in the through bore.

Surgical visualization systems and related methods are disclosed herein, e.g., for providing visualization during surgical procedures. Systems and methods herein can be used in a wide range of surgical procedures, including spinal surgeries such as minimally-invasive fusion or discectomy procedures. Systems and methods herein can include various features for enhancing end user experience, improving clinical outcomes, or reducing the invasiveness of a surgery. Exemplary features can include access port integration, hands-free operation, active and/or passive lens cleaning, adjustable camera depth, and many others.

Embodiments of a rotating assistant port device are presented. The assistant port device can be utilized to provide for additional assistant instruments in single port robotic surgery. In some embodiments, the assistant port device can be utilized for skin retraction during single port teleoperated robotic surgery.

A medical device is disclosed comprising an elongated needle assembly having a distal end, a proximal end and a longitudinal axis A, the needle assembly comprises a tubular cannula having a sharpened distal end, a proximal cannula portion, and a longitudinal bore along the longitudinal axis A,and a stylet configured to extend through the bore of the cannula,and having a blunt distal end and a proximal stylet portion. The needle assembly is provided with a spring member configured to urge the stylet in a distal direction along the longitudinal axis, such that the stylet is axially spring-biased in said distal direction. The medical device further comprises a connecting member configured to detachably attach said stylet to said cannula, wherein said stylet is configured to be attached to the tubular cannula by the connecting member such that the blunt distal end protrudes just beyond the sharpened distal end of the cannula when no force is applied to the distal end of the stylet in a proximal direction along said longitudinal axis, and wherein the connecting member is configured to enable detachment of the proximal portions from each other such that the stylet may be fully withdrawn from the longitudinal bore.

The present invention relates to a puncture device for creating a TIPS shunt, comprising a puncture needle, a sheath, the sheath being arranged to surround the puncture needle, the puncture needle being slidably arranged inside the sheath so that the puncture needle can be moved between a first position in which the puncture needle protrudes beyond the distal end of the sheath and a second position where a tip of the puncture needle is retracted into the sheath, the sheath and the puncture needle being arranged so that in the second position, blood can be aspirated into the sheath through a gap between the puncture needle and the sheath, a locking means, the locking means being arranged for releasably locking the puncture needle in the first and/or the second position.

The present disclosure relates generally to the field of medical devices and establishing access to a target within the body, such as placing an access needle into a renal capsule into the human body. In particular, the present disclosure relates to devices and methods for performing a percutaneous nephrolithotomy (PCNL) procedure accurately and efficiently while minimizing exposure of the medical professional to harmful radiation.

A method and a device for secured retrieval of tissue from inside a patient body and a kit comprising the device. the device comprises a tube housing a movable cutter. The cutter controllably extends from the tube while allowing continued fluid communication. The device comprises a retractable enclosure with a supporting frame linked to an impermeable membrane comprising an opening. Amplitude of the supporting frame is controlled. The opening in the impermeable membrane is unseal when enclosure is expanded and, when the tissue is positioned within the enclosure, the opening is sealably closed in the impermeable membrane. The moveable cutter morcellates the tissue into tissue specimens when the opening in the impermeable membrane is sealably closed while amplitude of the supporting frame is reduced to compress the tissue specimens and the tissue specimens are able to transit in the fluid communication channel through a discharging aperture after morcellation.

According to an aspect, a medical device includes an elongate member and a sleeve. The elongate member defines a lumen and has a first end portion and a second end portion. The second end portion has a first configuration and a second configuration. The second end portion has a first size when the second end portion is in its first configuration and a second size when the second end portion is in its second configuration. The first size is smaller than the second size. The second end portion is biased to its second configuration. The sleeve defines a lumen extending from a first end portion of the sleeve to a second end portion of the sleeve.

A cannula assembly can allow an operator in an arthroscopic surgical procedure to control both an arthroscope and a surgical tool with a single hand. In some embodiments, for example, a scope tube may be combined with a tool tube to allow such control. The tool may be manipulated, for example, by causing the tool to rotate, and/or to move forward and backward in relation to the cannula assembly.

A method of inserting an electrode into a cranial cavity of a cranium can include determining a length, between a target within the cranial cavity and a proximal end of a multipiece cannula, of the electrode for insertion of the electrode to the target. A distal end of the electrode can be inserted through a multipiece cannula supported by an instrument holder of a surgical arm. The surgical arm can be positioned such that a distance from the target to the proximal end of the cannula is equal to the length. The electrode can be fed through the cannula and through the anchor bolt into the cranial cavity. Feeding of the electrode through the cannula and into the cranial cavity can be stopped when the length of the electrode fed into the cavity reaches the length between the proximal opening of the multipiece cannula and the target.
