Surgical instruments and methods of minimally invasive surgery are provided. The device may include two proximal handles each sized for a surgeon's hand, the two handles in fixed relative positions, and a distal probe attached to the handles. The probe can include a distal cutting member and contain or receive an imaging device. The system can be used for cutting anatomic members, such as ligaments, during minimally invasive surgical procedures, for example, performing endoscopic ligament release surgery, such as carpal tunnel release, plantar fasciotomy, gastrocnemius release, cubital tunnel release, and tarsal tunnel release surgery, and similar surgical procedures on anatomic members.

A core material with a three-point support structure and tarsal bone correction shape is provided under the body temperature responsive polymer layer to achieve "responsiveness to the soles of each user's feet" and "improved tarsal bone correction effect." [Solution] Insole 1 has a substantially flat core material 3 beneath a body temperature responsive polymer layer 2. The body temperature responsive polymer layer 2 softens and deforms to fit the shape of the sole of the foot due to the user's body temperature, and core material 3 has a three-point support structure 4 and a tarsal bone correction shape 5. Furthermore, core material 3 is made of nylon 6 resin, and body temperature responsive polymer layer 2 has a non-slip portion 6, body temperature responsive polymer layer 2 returns to its initial shape after use, an elastic buffer layer 7 is provided between body temperature responsive polymer layer 2 and core material 3, core material 3 has a pressure dispersion shape, core material 3 has a vibration detection structure, and insole 1 does not have to have a built-in sensor, drive circuit, or drive power source. Insole 1 may also be used in footwear.

Devices, systems, and methods for surgical treatment of mid-foot disorders such as osteoarthritis, spacing disorders, or alignment disorders, including mid-foot arthroplasty devices and systems for the 2nd and 3rd tarsometatarsal (TMT) joint, implants for post-osteotomy spacing and realignment, arthroplasty articular implants, dowel grafts for TMT arthrodesis or fusion, dowel grafts for navicular cuneiform (NC) arthrodesis, dowel grafts for intercuneiform arthrodesis, and / or locking dowels for joint fusion.

This invention discloses a shoe last assembly, including a shoe last comprising a front part and a rear part. The front and rear parts of the shoe last form a detachable connection, with the connection point between them defined at a position corresponding to the tarsal bone of the foot. The foremost point along the length direction and the two lateral ends along the width direction of the shoe last are both located at the front part. One of the rear end of the front part and the front end of the rear part of the shoe last has a boss, and the other has a recess. Both the rear end of the front part and the front end of the rear part of the shoe last have contact surfaces. A screw passes between the front and rear parts of the shoe last. This invention's shoe last assembly allows for changing the style and size of the front end of the shoe last by disassembling and replacing the front part. It features a simple connection structure, convenient disassembly and replacement, a small gap at the connection point, and a smoother shoe last surface.

An insole core material for foot support. On the upper surface of the core material, multiple tarsal support portions are formed by three-dimensional ridges that provide corrective support for the skeletal alignment of the foot, corresponding to the positions and heights of multiple tarsal bones. When the upper, lower, or both surfaces of the core material have following grooves or following ridges that follow the movement between the tarsal support portions, it can flexibly accommodate flexion, internal rotation, and external rotation movements. A protruding structure, functioning as a corrective fulcrum, can be provided at a position corresponding to the lower part of the cuboid bone. On the lower, upper, or both surfaces of the core material, one or more reinforcing grooves can be provided to adjust the balance between the overall rigidity and flexural flexibility of the core material and to distribute pressure on the sole of the foot. Optimal support height is achieved by utilizing a structure extending to the base of the metatarsals and a setting based on a mathematical formula using correction coefficients.

This invention relates to the field of medical device technology, specifically to an osteotomy surgical device, comprising a fixable guide pin, a fixing nut, an osteotomy guide plate, a slotter, an oscillating saw slot, and a retractor. In use, the fixable guide pin is first inserted through the tarsal canal, and the fixing nut is installed on the medial side of the foot. The depth of the entire tarsal canal is read using the first graduation mark on the fixable guide pin. The osteotomy guide plate is placed on the fixable guide pin, and 1.5mm Kirschner wires are inserted into the fixing holes on both sides for auxiliary fixation. Osteotomy is precisely performed with the assistance of the osteotomy guide plate. After osteotomy, the fixable guide pin and osteotomy guide plate are removed. The slotter is inserted into the osteotomy site and its bottom is tapped. The oscillating saw slot is inserted according to the length of the tarsal canal, and the oscillating saw is used. The retractor is inserted, and the handle is used to open the tarsal canal to the required angle, which is read from a graduated slide rail. This allows for precise positioning of the tarsal canal while meeting the osteotomy depth and opening angle requirements.

The utility model relates to the technical field of animal experiment auxiliary devices, solves the problem that in the prior art, the animal fixing mode is low in efficiency, and discloses a rat intramuscular injection auxiliary device which comprises a bottom plate, a plurality of fixing assemblies and a plurality of tarsal bone fixing parts. The fixing assembly comprises a base and two fixing frames. The fixing frame is arc-shaped; one end of each fixing frame is connected with one side of the base, and the other end of each fixing frame extends away from the base; a fixing space for wrapping the trunk of the rat is formed between the two fixing frames; the plurality of bases are arranged on the bottom plate at intervals; one fixing assembly and two tarsal bone fixing parts form one group; in each group, the tarsal bone fixing pieces are arranged on the bottom plate at intervals. Through combined use of the multiple fixing assemblies and the tarsal bone fixing part, stable fixing of multiple rats is achieved.
