Description

Technical Field

[0001] The invention relates to the field of medical device technology, and more specifically, to a cyst dissector. Background Art

[0002] Subcutaneous cysts are common and frequently occurring diseases on the body surface. The treatment is surgical excision. Hemostatic forceps and small scissors are often used to peel off the cyst during the operation. Due to the lack of suitable peeling instruments, the cyst peeling process is too complicated, which prolongs the operation time and may even easily cause the cyst wall to rupture, resulting in greater trauma. In addition, it may also lead to the inability to completely remove the cyst, resulting in residual cyst wall and cyst recurrence.

[0003] Therefore, we propose a cyst dissector to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a cyst dissector.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A cyst stripper comprises a handle rod which is open at one end and hollow, an adjusting rod being connected to the handle rod through an internal thread, one end of the adjusting rod passing through the handle rod and being fixedly connected to the handle, the inner wall of the handle rod and the outer wall of the adjusting rod being both provided with threads, an end of the adjusting rod away from the handle being fixedly connected to a connecting rod, an end of the connecting rod away from the adjusting rod passing through the handle rod and being fixedly connected to a stripping ring, and a through hole corresponding to the connecting rod being provided at the end of the handle rod away from the adjusting rod.

[0006] Preferably, the outer side wall of the handle rod, the end of the handle rod close to the stripping ring, the outer side wall of the connecting rod and the outer side wall of the stripping ring are all rounded.

[0007] Preferably, an outer side wall of one end of the handle rod close to the handle is provided with anti-slip patterns.

[0008] The technical solution provided by the embodiments of the present invention can include the following beneficial effects: In the patent of the present invention, the stripping ring installed at one end of the connecting rod performs extrusion-type stripping on the subcutaneous cyst during use. The cyst is in a safe area within the stripping ring, and the pressing area of ​​the stripping ring separates the normal tissue around the cyst wall to avoid causing greater trauma. In addition, the cyst can be completely removed to reduce the risk of recurrence.

[0009] In the patent of the present invention, the connecting rod is made of plastic metal material, and the angle of the stripping ring can be adjusted according to the needs of the surgical site, thereby improving the application range of the cyst stripper. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic diagram of the structure of the cyst dissector proposed in the present invention; Figure 2 This is a schematic diagram of the internal structure of the cyst dissector proposed in the patent of this invention.

[0011] In the figure: 1. handle rod; 2. adjustment rod; 3. handle; 4. connecting rod; 5. stripping ring; 6. thread; 7. anti-slip pattern. DETAILED DESCRIPTION

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0013] Reference Figure 1-2 The cyst dissector comprises a handle bar 1 which is open at one end and hollow, an adjusting bar 2 is connected with the inner thread of the handle bar 1, one end of the adjusting bar 2 penetrates the handle bar 1 and is fixedly connected with a handle 3, the inner wall of the handle bar 1 and the outer wall of the adjusting bar 2 are both provided with threads 6, the length of the adjusting bar 2 entering into the handle bar 1 can be adjusted by rotating the handle 3, and then the overall length of the cyst dissector is adjusted, the end of the adjusting bar 2 away from the handle 3 is fixedly connected with a connecting bar 4, the end of the connecting bar 4 away from the adjusting bar 2 penetrates the handle bar 1 and is fixedly connected with a stripping ring 5, and the end of the handle bar 1 away from the adjusting bar 2 is provided with a through hole corresponding to the connecting rod 4, the length of the adjusting bar 2 entering into the handle bar 1 can be adjusted by rotating the handle 3, so as to adjust the overall length of the cyst dissector according to the use requirements of the surgical site, the stripping ring 5 functions to perform extrusion stripping of the subcutaneous cyst, the cyst is in a safe area in the stripping ring 5, and the pressing area of ​​the stripping ring 5 separates the surrounding normal tissue of the cyst wall to avoid causing greater trauma, in addition, the cyst can be completely removed to reduce the risk of recurrence.

[0014] In the patent of the present invention, more specifically, the material of the connecting rod 4 is a plastic metal material. During use, the shape of the connecting rod 4 can be bent as needed to facilitate the stripping ring 5 to separate the surrounding normal tissue of the cyst wall.

[0015] In the present invention, more specifically, the outer wall of the handle rod 1, the end of the handle rod 1 close to the stripping ring 5, the outer wall of the connecting rod 4 and the outer wall of the stripping ring 5 are all rounded.

[0016] In the patent of the present invention, more specifically, an outer wall of the handle rod 1 at one end close to the handle 3 is provided with an anti-slip pattern 7, and the function of the anti-slip pattern 7 is to increase the friction between the doctor's hand and the cyst dissector.

[0017] In the patent of the present invention, when performing surgical treatment on subcutaneous cysts, the length of the adjusting rod 2 entering the handle rod 1 is adjusted according to the requirements of the operation, and then the connecting rod 4 is bent according to the position of the cyst, and the angle of the stripping ring 5 is adjusted to facilitate more convenient removal of the cyst. During the process of removing the cyst, the cyst is in a safe area within the stripping ring 5, and the pressing area of ​​the stripping ring 5 separates the normal tissue surrounding the cyst wall, thereby completing the stripping and removal of the cyst, avoiding causing greater trauma and reducing the risk of recurrence.

[0018] The above is only a preferred specific implementation method of the patent of the present invention, but the protection scope of the patent of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme of the patent and the invention concept of the patent within the technical scope disclosed by the patent of the present invention, which should be covered by the protection scope of the patent of the present invention.
