A soluble needle (100) for hair transplantation, wherein the soluble needle (100) comprises a fixing plate (30) and a plurality of micro-needles (20) made of water-soluble polymers arranged on the fixing plate (30), wherein each of said micro-needle (20) comprises a needle wall (21) to penetrate scalps and a needle cavity (22) confined by the needle wall (21) and configured for accommodating a hair follicle. A method of manufacturing a soluble needle (100) for hair transplantation, wherein the method includes: dissolving water-soluble polymers in water to prepare a molding solution (S101); delivering the molding solution into a mold (S102); letting the molding solution settle in the mold to shape (S103); and separating and removing the mold to produce the soluble needle (S104). The soluble needle (100) effectively shortens the time of surgery, reduces the pain of the patients, and increases the viability rate of transplanted hair follicles.

Method and apparatus for tissue grafting

Exemplary embodiments of apparatus and method for harvesting small portions of tissue (“micrografts”) to form grafts can be provided. For example, a hollow tube can be inserted into tissue at a donor site, where a distal end of the hollow tube can have two or more points or extensions to facilitate separation of the micrografts from the surrounding tissue. The exemplary apparatus can be provided that includes a plurality of such tubes for simultaneous harvesting of a plurality of micrografts. The harvested micrografts can have a small dimension, e.g., less than about 1 mm, or less than about 0.3 mm, which can promote healing of the donor site and/or viability of the harvested tissue. The micrografts can be approximately cylindrical or strip-shaped, and can be placed in a biocompatible matrix to form a graft or directly into tissue at the recipient site. Such exemplary micrografts can be obtained from skin or other types of tissue, e.g., various internal organs.

A METHOD OF DETERMINING A POSITION AND/OR ORIENTATION OF A HAND-HELD DEVICE WITH RESPECT TO A SUBJECT, A CORRESPONDING APPARATUS AND A COMPUTER PROGRAM PRODUCT

According to an aspect, there is provided a method of determining a position and/or orientation of a hand-held device with respect to a subject. The hand-held device is for use on a body of the subject. The method comprises receiving (101) images from an imaging unit arranged in or on the hand-held device; receiving (103) a displacement signal from a displacement sensor that is arranged in or on the hand-held device to measure displacement of the hand-held device along the body when the hand-held device is in contact with the body; processing (105) the received images to determine whether a body part of the subject can be identified in the received images; determining (107) whether the hand-held device is in contact with the body; determining (109) a mode of operation to use to determine a position and/or orientation of the hand-held device based on whether a body part can be identified and whether the hand-held device is in contact with the body; wherein the mode of operation to use is determined as (i) a first mode when a body part can be identified, (ii) a second mode when a body part cannot be identified and the hand-held device is not in contact with the body, and (iii) a third mode when the hand-held device is in contact with the body; and determining (111) the position and/or orientation of the hand-held device with respect to the body of the subject using the received images and/or received displacement signal according to the determined mode of operation.

Methods and systems for directing movement of a tool in hair transplantation procedures

Methods and systems are provided useful in various procedures, including hair harvesting and implantation, and further including computer-implemented and/or robotic hair transplantation. Methodologies are provided which enable a tool, such as a hair harvesting or a hair implantation tool, to proceed at least under a partial computer control in a selected direction of travel along a donor or recipient area of the patient, as well as changing direction of travel based on desired harvesting and/or implantation criteria.

Attachment for epilator and epilator

The present disclosure is concerned with an attachment for an epilator or an epilator having an axle arranged for driven movement around a center axle axis, an end plate arranged at a first end of the axle for rotation together with the axle, the end plate having at least a first functional surface, a first clamping element having a functional surface, the first functional surface of the end plate being arranged face-to-face with the functional surface of the first clamping element, and the first clamping element being arranged for repeatedly being moved towards and away from the end plate such that repeatedly a closed position is obtained in which the two functional surfaces abut on each other, wherein the end plate is an outer part of the epilator or the attachment for an epilator.
