Description

Technical Field

[0001] The utility model relates to the technical field of tenothecintomy and release treatment equipment, in particular to a tenothecin release sheath device for endoscope-assisted tenothecintomy and release. Background Art

[0002] As an advanced minimally invasive technique, the tenotomy and release technique under endoscopic monitoring has been widely used in orthopedic surgery. For example, in the tenotomy of the hand, the endoscope needs to be inserted into the surface of the tendon sheath through the skin opening. However, due to the dense subcutaneous tissue of the hand, and the frequent adhesion and scar tissue formation in the affected area, the insertion of the lens is very difficult. Therefore, the help of a sheath (cannula) is often needed to allow the lens and the tool to penetrate the skin and subcutaneous tissue smoothly, and to provide a certain degree of protection for the lens during the process. Secondly, since the endoscope requires a certain amount of space under the skin to be flexibly operated, and the lens used in the tenotomy and release technique is very small, there is no matching sheath on the market. Therefore, a sheath device that matches the tenotomy and release technique is needed to meet the needs. Utility Model Content

[0021] The utility model aims to solve the problem that there is no sheath tube that can guide the lens and the tool to the designated position in the current clinical tendon sheath incision and release technology. Figure 1-4 As shown, the following technical solution is provided: a tendon sheath release sheath device for endoscopically assisted tenotomy and release, comprising: a handle portion 1 and a sheath portion 2, wherein the first end of the sheath portion 2 is rotatably connected to one end of the handle portion 1, the bottom of the sheath portion 2 has a channel groove 5, and the channel groove 5 is open near one end of the handle portion 1. The sheath portion 2 can be smoothly inserted into the skin and extend into the subcutaneous tissue under the operation of the handle portion 1, and the channel groove 5 leaves space for a lens and a tool to pass through. After the handle portion 1 is rotated and folded, it will not affect the lens and the tool from entering the channel groove 5.

[0022] Specifically, Figure 2 As shown, when the angle between the handle part 1 and the sheath part 2 is 180°, the handle part 1 can be held, the sheath part 2 can be inserted into the skin, and the handle part can be lifted up after insertion, so that the sheath and the skin covering the sheath can be lifted up, thus stretching the subcutaneous space, which is not only conducive to the penetration of the lens, but also convenient for the operation of the lens under the skin, and expands the field of view of the lens. After the sheath part 2 is inserted into place, the handle part 1 can also be rotated around the sheath part 2, and the angle between the two can be rotated to less than 90 degrees, so that there are no obstacles around the opening end of the channel groove 5, which facilitates the lens and the tool to enter the channel groove 5. The width and depth of the channel groove 5 are both ≥3mm, ensuring that the lens and the tool can pass through the channel groove 5 smoothly.
