Description

Technical Field

[0001] The utility model specifically relates to a mesh cutter. Background Art

[0002] Female pelvic organ prolapse is a type of abnormal position and function of pelvic organs caused by abnormal pelvic floor muscles and fascia tissues. The main clinical manifestations are prolapse of vulva, lower urinary tract symptoms and defecation disorders, which affect the quality of life of patients to varying degrees. At present, mesh is generally used to repair pelvic floor organs in clinical practice. Different surgical methods require specific surgical instruments to ensure that the mesh of the right size is fixed on the patient's autologous tissue through the obturator path.

[0003] The mesh used in pelvic organ prolapse repair surgery is often a one-piece mesh or a self-cut mesh. The mesh is usually of standard specifications, but due to individual differences in patients and surgical needs, the patient's prolapse condition needs to be evaluated before and during surgery, and then the mesh is cut to the appropriate size. The manual cutting process has errors, which not only requires cooperation between multiple surgeons, but also affects the overall time of the operation, and may also cause injuries to the surgeon during the cutting process. Utility Model Content

[0004] The utility model aims to provide a mesh cutter to solve the shortcomings of large error and low efficiency in manual mesh cutting in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A mesh cutter comprises a working plate and a tool assembly; a slide groove is fixed on the working plate; the tool assembly is fixed on the slide groove of the working plate, so that the tool assembly moves on the slide groove to cut the mesh.

[0007] In the utility model, the tool assembly includes a knob, a handle, a blade, a slider and a gasket; the slider and the gasket are both provided with through holes, and the slider and the gasket are fixedly connected; the gasket passes through the slide groove so that the slider is limited in the slide groove; the knob is connected through the handle and the blade, and the handle and the blade are arranged through the through holes of the slider and the gasket.

[0008] Furthermore, the through hole is a square hole.

[0009] The utility model can be improved as follows: the knife assembly further comprises a spring, one end of which is connected to the knife handle, and the other end is connected to the blade. By providing the spring, the blade can be brought into contact with the mesh only when the knob is pressed, thereby avoiding cutting errors and knife stabs to the operator when the mesh cutter is moved.

[0010] In the utility model, the working plate is also provided with a groove for placing the mesh.

[0011] The utility model also includes a ruler, which is fixed on the working board. The size of the cut mesh can be better confirmed by the ruler.

[0012] Furthermore, there are two rulers, which are vertically arranged.

[0013] In the utility model, the material of the mesh cutter is stainless steel.

[0014] The utility model has the following beneficial effects:

[0015] (1) Compared with manual mesh cutting, which requires measuring a certain size with a ruler and then cutting with scissors, the mesh cutter of the utility model has higher precision, and the cut mesh is more closely matched to the size required by the patient; at the same time, it can reduce the operation time, is easy to operate, and has a simple and easy-to-understand design, which greatly improves the efficiency of the surgeon in cutting the mesh.

[0016] (2) The utility model mesh cutter avoids the risk of injury that may occur when the surgeon uses scissors to cut directly, thus avoiding iatrogenic injury; the cut mesh is suitable for the mesh shape required in different surgical methods and has strong adaptability; the stainless steel material used can be recycled after disinfection, reducing long-term maintenance and replacement costs.

[0023] like Figure 1-4The mesh cutter shown includes a working plate 1 , a cutter assembly 2 , a first ruler 3 and a second ruler 4 .

[0024] A first ruler 3 is fixed on the left side of the working board 1, and a second ruler 4 is fixed below. The first ruler 3 and the second ruler 4 are arranged vertically, with a ruler 15 cm long. The working board 1 is provided with a groove 101, and the size of the groove 101 is 7.5*15*0.3cm, which can meet the placement of meshes of different specifications. The mesh is placed in the working board 1 by folding in half. There is a slide 102 in the groove 101, and the tool assembly 2 is movably connected to the slide 102. The rulers on both sides of the working board 1 can be used to measure the length of the mesh. According to the preoperative and intraoperative evaluation of the patient, the specific shape of the mesh is determined. By moving the placement position of the mesh, the tool assembly 2 on the slide 102 and the first ruler 3 and the second ruler 4 are used to cut the mesh. The shape of the slide groove 102 is consistent with the shape of the mesh commonly used by the surgeon. Compared with the existing one-piece mesh, the self-cut mesh is cheaper, but self-cutting often has large errors and requires mutual cooperation between surgeons. The utility model uses the slide groove 102 to achieve precise cutting of the mesh and reduce the loss of the mesh.

[0025] In this embodiment, the tool assembly 2 is an integrated type, including a knob 201, a handle 202, a blade 204, a slider 205 and a gasket 206. The blade 204 is 2 mm wide and 3 mm long. Both the slider 205 and the gasket 206 are provided with through holes, which are square holes, and the slider 205 and the gasket 206 are fixedly connected; the gasket 206 passes through the slide groove 102, so that the slider 205 is limited in the slide groove 102 and can move on the slide groove 102; the knob 201 is connected to the blade 204 through the handle 202, and the handle 202 and the blade 204 are arranged through the through holes of the slider 205 and the gasket 206. In this embodiment, the tool assembly 2 also includes a spring 203, one end of the spring 203 is connected to the handle 202, and the other end is connected to the blade 204. By setting the spring 203, when the cutter is pressed downward, the knob 201 is pressed to make the blade 204 contact the mesh, so as to avoid cutting errors and knife stabs to the operator when the mesh cutter is moved. The cutter assembly 2 realizes the change of the direction of the blade 204 through the knob 201 at the upper end, and realizes the sliding of the cutter assembly 2 on the chute 102 through the slider 205. At the same time, when the chute 102 turns, release the pressing, twist the knob 201 at the upper end, ensure that the blade 204 rotates 90 degrees as a whole and coincides with the central through hole of the gasket 206, ensure that the direction of the blade 204 is always consistent with the sliding direction of the cutter assembly 2, so as to facilitate cutting, and then continue to press the knob 201 structure to ensure that the cutter contacts the mesh for cutting.

[0026] The mesh cutter in the utility model is made of stainless steel. The stainless steel material can make the surface of the working plate 1 and the slide 102 have good corrosion resistance, and can exert the inherent surface properties of stainless steel without surface treatment such as plating, and has excellent heat resistance. The working plate, ruler and knife of this embodiment are sterilized with ethylene oxide and can be recycled after disinfection and sterilization. The mesh cutter of the utility model can greatly improve the convenience and efficiency of surgery.

[0027] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these. All other various forms of modifications, replacements or changes made to the above-mentioned structure of the utility model based on the above-mentioned contents of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the utility model, should fall within the protection scope of the utility model.
