The invention discloses a prosthesis positioner for mammary gland prosthesis reconstruction, and relates to the technical field of mammary gland prosthesis positioners, the prosthesis positioner comprises a main body mechanism, the main body mechanism comprises a fixing support, four pairs of supporting plates are arranged on the outer side of the fixing support, and a positioning adjusting mechanism is arranged on the outer side of the fixing support; the positioning adjusting mechanism comprises an incision adjusting unit, the incision adjusting unit is located on the outer side of the supporting plate, and the incision adjusting unit is used for adjusting the size of an incision to a certain extent according to the operation requirement of a patient. The angle and the distance of the supporting plate can be adjusted through the driving motor, the lifting rack and other structures, so that the size of an incision is flexibly adjusted according to the specific operation requirement of a patient, and the problem that the operation is limited due to the fact that the incision space of a traditional positioner is fixed is effectively solved; therefore, the requirements of different patient chest radians and surgical incision positions can be met.

Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.

A graft system comprising: a graft body having an incision or opening in a side surface through which a support structure is insertable; and a filling structure surrounding at least part of the graft body, defining an internal volume fillable with a filling medium, and having a conduit through which the support structure is insertable, the filling structure comprising: a baffle configured to be fillable with a filling medium, and a window having a width greater than the width of the support structure, and partially opening the graft body prior to filling the baffle with the filling medium; and when the support structure is disposed within the window, the baffle expanded by filling with the filling medium reaches an outer surface of the support structure to form the duct; and when the support structure is not disposed within the window, a baffle expanded by filling with a filling medium completely seals the window.

Various types of incision control devices secure tissue surrounding and / or adjacent to a target incision site and maintain the size of the incision through a single wall of a vessel, organ, or lumen within the body. Among other things, this can reduce unintended trauma, dilation, contraction, or migration of the incision during a surgical procedure. They can also serve the beneficial purpose of allowing immediate communication between lumens prior to the complete creation of a permanent anastomosis. In some embodiments, magnetic compression anastomosis devices and / or other devices can be deployed through a channel in the incision control device, such as for deployment within the distal lumen.

A system for treating glaucoma is disclosed that includes a modular tube diverter implant having a flexible plate and a separable fluid drainage tube that are separately inserted and connected after insertion. The system includes a tube inserter featuring a delivery cannula having a needle tip-like distal end and a plunger having a pop-up rod configured to pierce the sclera and deliver the tube into the anterior chamber. A plate inserter, also including a cannula and a plunger, is configured to deploy the flexible plate in a compact form through the same small conjunctival incision, where the flexible plate is deployed to fit over the sclera. The connecting mechanism can easily connect the plate and the pipe through the notch. The system is specially designed for minimally invasive surgery, and therefore efficient deployment of the two components is achieved through the small-diameter cannula, and tissue damage and recovery time are reduced.

A surgical access system (1) adapted to facilitate access to a surgical site through an incision in a patient's body upon opening the incision comprises a support ring (2), a radially adjustable saddle-shaped retractor (3, 17) configured to grasp and manually retract a section of abdominal tissue into the incision, and coupling elements (20) configured to adapt each of the radially adjustable saddle-shaped retractors to the support ring in a tissue retraction position. The system (1) is adapted to facilitate access to a neonate through a cesarean section incision in the patient's abdomen.The support ring is sized to allow the delivery of a neonate through the ring and comprises a non-adjustable saddle-shaped retractor (7) fixed to the support ring and an outward-projecting handle (8) fixed to the support ring adjacent to the fixed saddle-shaped retractor (7). The non-adjustable saddle-shaped retractor is a pelvic region retractor configured to cover and retain the woman's bladder during a cesarean section. The coupling element for the radially adjustable saddle-shaped retractor comprises a first formation disposed on the upper portion of the support ring and a corresponding second formation on the retractor configured to engage with the first formation, wherein the formations are configured to allow the retractor to tilt and / or rotate relative to the support ring when the retractor is fitted to the ring in a tissue retraction position.

Method for controlling an ophthalmic surgical laser (18) for separating at least one volume body (12) with a predefined posterior interface (14) and a predefined anterior interface (16) from a human or animal cornea (32), comprising: - controlling the laser (18) by means of a control device (20) such that it emits pulsed laser pulses into the cornea (32) in a predefined pattern, wherein the control device (20) controls the laser beam (24) such that the volume body (12) is divided into at least two individual bodies (38, 40, 42) by means of photodisruption through an interaction of the individual laser pulses with the cornea (32), and the totality of the individual bodies (38, 40, 42) includes the posterior and anterior interfaces (14, 16) of the volume body (12), and wherein the laser (18) is controlled in this manner becomes,that at least one cut (36) or at least one opening is produced in the cornea (32) at a predefined angle and / or with a predefined geometry, wherein the cut (36) or the opening intersects an interface (14, 16) of the volume body (12) and extends to a surface (26) of the cornea (32) such that the individual bodies (38, 40, 42) of the volume body (12) can be removed from the cornea (32) via the cut (36) or the opening, and wherein the surface (26) of the cornea (32) is an artificially created surface of the eye by removing or moving an uppermost corneal layer and / or by producing a corneal flap.

A method of preventing tissue adhesion includes forming an incision in tissue, applying a hydrogel to tissue through the incision, and closing the incision with the hydrogel therein. The hydrogel includes a polymer non-covalently cross-linked with a plurality of nanoparticles and prevents a formation of adhesions between tissues and / or organs.
