The invention relates to a method and device for developing the size of a phakic vision correction implant for the eye (3) of a patient. From a horizontal section (6) of the anterior segment of the eye and an optical power Po, we determine (34) the size of several implants from a basis Ii, we geometrically simulate (35) the image of the respective positions of these implants on reconstructed surfaces s1, s2, ...si of the section, then we calculate (37) for each size of implant Ii, the value Vtsci of the theoretical Vault without compression and the total theoretical compression CTi, we calculate (42) the probability of obtaining a satisfactory Vault between two threshold values ​​S1 and S2 by considering the cases of operated patients for whom the respective differences between their Vtsci and the postoperative Vaults for a given compression CTi have been calculated, and we choose (43) the size of implant presenting the highest probability between S1 and S2.Figure for the abridged version: Fig. 1.

The invention relates to a method and device for determining the size of a phakic corrective implant for correcting the vision of the eye (3) of a patient. On the basis of a horizontal section (6) of the anterior segment of the eye and an optical power Po, the size of a plurality of implants taken from a base Ii is determined (34), the image of the respective positions of these implants is geometrically simulated (35) on reconstructed curves s1, s2,...si of the section, then the value Vtsci of the theoretical vault without compression and the total theoretical compression CTi are calculated (37), the probability of obtaining a satisfactory vault between two threshold values S1 and S2 is calculated (42) by taking into consideration the cases of patients who have been operated for whom the respective differences between their Vtsci and vaults postoperatively for a given compression CTi have been calculated, and the implant size that has the highest probability between S1 and S2 is selected (43).

This application provides an adaptive biodegradable implant shaping patch for breast reconstruction, belonging to the fields of medical biodegradable materials and breast reconstruction medical devices. It includes an arc-shaped cover and a base cover that unfold into a porous, sheet-like integrated structure. The arc-shaped cover contains a radially distributed array of flaps around a central reference point and an elastic buffer zone located between the central reference point and the root of the flap array. The flap array bends and encloses to form a hemispherical covering space that conforms to the outer curved surface of the implant. The base cover is a disc-shaped structure that adapts to and covers the lower end face of the implant, and connects to the extended ends of the flaps to achieve conformal coverage. This invention's patch has a reasonable structure, good fit to the implant, can simulate the physiological and mechanical characteristics of the breast, is easy to operate, and provides reliable fixation. It can adapt to different implant sizes and can reduce postoperative complications, meeting the personalized breast reconstruction needs of different patients, and has high clinical application value.

A drill component is provided that enables determining the drill component's insertion depth into bone via direct measurements. The direct measurements help provide more consistently accurate insertion depth measurements as compared to typical insertion depth measurement methods that indirectly determine insertion depth using cannulas outside of the bone. The determined insertion depth corresponds to an implant size or length that a surgeon should select for a procedure. The drill component includes a shaft having an insertion end that includes multiple indications or markings that are visible on radiographic or fluoroscopic images. From one or more captured radiographic or fluoroscopic images of the drill component advanced into bone, a surgeon may count a quantity of indications or markings of the drill component on the one or more radiographic or fluoroscopic images to determine the drill component's insertion depth into the bone.

This application relates to an implantation device and implantation system. The implantation device includes an implantation rod, an implantation sleeve, and a tracking mounting platform. The implantation sleeve includes a first sleeve portion and a second sleeve portion. The inner diameter of the first sleeve portion is adapted to the diameter of the implantation rod, and the inner diameter of the second sleeve portion is larger than the diameter of the implantation rod. The implantation rod passes through the first sleeve portion and extends into the second sleeve portion. The inner diameter of the second sleeve portion is adapted to the size of the implant. The implantation rod includes an implantation end and a connecting end. The implantation end and the connecting end are located at opposite ends of the implantation rod and on both sides of the first sleeve portion. The connecting end is used to connect to a structure that provides power to the implantation rod. The implantation end is located within the second sleeve portion and is used for detachable connection to the implant. The implantation rod also passes through the tracking mounting platform. The tracking mounting platform is used to mount a tracking device. The tracking device is used to determine the overall pose of the implantation device after identification. According to the above embodiment, the problem of complex implantation device structures can be solved.

The utility model relates to a rapid fixing bone grafting mold, which belongs to the technical field of medical instruments and comprises a box body, a main shaft and a clamping component are mounted on the box body, the main shaft is rotatably connected with the box body, and the clamping component is slidably connected with the box body; a spiral groove is formed in the main shaft, the clamping assembly is meshed with the groove in the main shaft, and one end of the main shaft is fixedly connected with the knob; scale sizes are uniformly arranged on the circumference of the knob and correspond to the size of an implant which can be clamped; the rotary knob is rotated to the corresponding scale size according to the implant size, the rotary knob drives the main shaft to rotate together, and the clamping assembly moves in the axial direction of the main shaft through the groove, so that the implant is clamped; according to the utility model, the knob can be rotated to the corresponding scale size according to the size of the implant, so that the clamping component moves along the axial direction of the main shaft so as to clamp the implant, the clamping force can be accurately quantified by virtue of the scale size on the knob, the implant is prevented from being excessively pressed to cause indentation or deformation, and the implant is quickly fixed and positioned.

The invention relates to an auxiliary medical device (40) for delivering an implant (I) into the body of a patient. The implant may be a duodenal anchor (20) and / or a gastric anchor (10). The auxiliary medical device includes at least one wing member (81, 82), a support member (90), a release wire (50), and a narrowing mechanism (60). The at least one wing member (81, 82) and the support member (90) are releasably connected or connectable together by a release wire (50) to form a generally annular cross-section. A narrowing mechanism (60) is adapted to at least partially narrow the annular cross-section. The release wire (50) is arranged such that when the release wire (50) is pulled, the connection between the at least one wing member (81, 82) and the support member (90) is released.
