Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an anorectal hemostasis and stripping device. Background Art

[0002] Hemostatic forceps and stripping scissors are commonly used medical instruments during surgery. Hemostatic forceps are primarily used to clamp blood vessels or tissues, preventing blood flow and providing a clear field of view for the surgeon. They resemble a pair of slender pliers, with fine teeth at the front for clamping blood vessels and tissues, and a locking mechanism at the back to stabilize the opening and closing of the forceps. The teeth and locking mechanism work together to stably clamp blood vessels. Stripping scissors are primarily used for dissecting and separating tissues, and are often used for dissecting loose tissues, such as normal anatomical spaces, loose adhesions, benign tumors, or the extracapsular space of cysts. Stripping scissors typically consist of two shear blades connected by a central hinge.

[0003] However, during surgery, especially for mixed hemorrhoids treated with external and internal ligation, the patient must assume the lithotomy or lateral decubitus position, undergo local disinfection, and undergo infiltration or lumbar anesthesia to fully expose the hemorrhoid. A V-shaped skin incision is made on the external hemorrhoid. A vascular clamp is used to bluntly dissect the subcutaneous venous plexus of the external hemorrhoid, extending it to 0.3 cm below the dentate line. A curved vascular clamp is then used to clamp the dissected external hemorrhoidal flap and the base of the internal hemorrhoid. A thick silk thread is passed through the center of the internal hemorrhoid base to create an O-shaped ligature. The skin and venous plexus within the V-shaped incision are then trimmed, leaving a radial wound at the anus. The anus is rich in blood vessels and nerves, the anorectal surgical field is complex and narrow, and the surgical site is fragile and rich in capillaries, making it prone to bleeding. To prevent bleeding from obstructing the surgeon's field of view and thus hindering the surgical process, the surgeon must repeatedly use hemostatic forceps and dissecting scissors to stop bleeding and dissect tissue, which greatly inconveniences the surgeon's precise surgical technique. Summary of the Invention

[0004] The present invention discloses an anorectal hemostatic and stripping device, which is intended to solve the technical problem that in the above-mentioned anorectal surgery, doctors need to repeatedly take and use hemostatic forceps and stripping scissors alternately, which is inconvenient in operation.

[0005] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present invention are as follows:

[0006] An anorectal hemostasis and stripping device comprises two rotatably connected scissor bodies, each of the scissor bodies comprises a scissor head, the upper and lower end faces of each scissor head are bent inward and extend toward the other scissor head, and the two inwardly extending ends of each scissor head are respectively provided with a hemostasis surface and a stripping surface, and the two hemostasis surfaces are arranged opposite to each other to form a hemostasis part, and the two stripping surfaces are arranged opposite to each other to form a stripping part.

[0007] After adopting this technical solution, the upper and lower end surfaces of the scissors head are extended, and a hemostatic surface and a stripping surface are respectively provided on the two ends of the extension, forming a hemostatic part and a stripping part respectively with the hemostatic surface and the stripping surface of the other scissors head. The hemostatic part and the stripping part are then arranged relative to each other, that is, the hemostatic part and the stripping part are respectively provided on the upper and lower end surfaces of the scissors body. The doctor can adopt the method of moving away - turning the wrist - re-clamping to achieve the transition between the stripping function and the hemostatic function according to the progress of the mixed hemorrhoid external stripping and internal ligation surgery, without having to repeatedly pick up and alternately use the hemostatic forceps and the stripping shears during the surgery, thus making it more convenient for the doctor to use the device. At the same time, because the doctor does not need to repeatedly pick up and replace the hemostatic forceps and the stripping shears when using the device, the doctor can also improve the efficiency of the surgery and reduce the operation time when performing the mixed hemorrhoid external stripping and internal ligation surgery using the device.

[0008] The upper and lower end surfaces of the scissor head extend toward the other scissor head, and a hemostatic surface and a peeling surface are respectively provided on the extended parts. This arrangement creates a gap between the hemostatic surface and the peeling surface. This gap can ensure the normal use of the hemostatic surface and the peeling surface, so that the hemostatic part and the peeling part of the device can be used normally without interfering with each other, thereby improving the doctor's experience in using the device.

[0009] Among them, the scissors head includes a straight part and a curved part connected to the straight part, the curved part is bent upward, and the straight part and the curved part together constitute a curved structure of the scissors head, the hemostatic part is arranged on the inner side of the curved structure of the scissors head, and the stripping part is arranged on the outer side of the curved structure of the scissors head.

[0010] After adopting this technical solution, the setting of the curved part and the straight part makes the overall shape of the scissors head become a curved shape with a slightly arc-shaped front end. This curved shape can cooperate with the curved shape structure of the anorectal. When the scissors head is extended into the anorectal through the anus, the curved shape of the front end of the scissors head can better fit with the anorectal wall, clamping the hemorrhoids on the anorectal wall and improving the stability of clamping the hemorrhoids on the anorectal wall.

[0011] The arrangement of arranging the hemostatic portion on the inner side of the curved structure and the stripping portion on the outer side of the curved structure facilitates the cutting of mixed hemorrhoids by the stripping portion. Since the front end of the scissors head is the curved portion, the curved portion will not directly contact other intestinal walls that do not need to be cut, thereby preventing damage to the intestinal walls that do not need to be cut, thereby ensuring safety during the operation. When the stripping portion of the curved portion is used to cut and strip the external hemorrhoid, the blade of the scissors head on the curved portion can better adjust the angle to fit the mixed hemorrhoid compared to the blade of the scissors head on the straight portion. The doctor can better control the force and angle when using the scissors head. Therefore, the mixed hemorrhoids can be cut more precisely, thereby improving the cutting accuracy of the mixed hemorrhoids.

[0012] The length of the scissors body is 15-18 cm, and the thickness, length and width of the scissors head are 3-5 cm, 5-6 cm and 0.5-1.5 cm, respectively.

[0013] After adopting this technical solution, the overall length of the scissors body is longer, the width of the scissors head is narrower, and the thickness of the scissors head is increased. First, by changing the thickness of the scissors head, the distance between the upper and lower end faces can be changed. By changing the distance between the upper and lower end faces, the position between the hemostatic part and the stripping part can be changed, so as to ensure the normal use of the hemostatic part and the stripping part. Secondly, the overall length of the scissors body is longer and the width is narrower, which matches the position of the external and internal hemorrhoids of mixed hemorrhoids and is suitable for the external stripping and internal ligation of mixed hemorrhoids, which can improve the doctor's hand feeling when using this device for external stripping and internal ligation. At the same time, it can match the curved structure of the anorectal, so that the scissors body can penetrate deep into the anorectal, clamp and stop bleeding of the mixed hemorrhoids and internal hemorrhoids on the anorectal wall, and facilitate ligation. Finally, by increasing the thickness of the scissors head and setting a hollow structure, the hemostatic surface and the stripping surface can be used without interfering with each other, so that the operation can be carried out smoothly.

[0014] Wherein, the bending angle of the curved portion of the scissors head is 15-30°.

[0015] After adopting this technical solution, the bending angle of the curved part is limited, so that the curved part is only slightly arc-shaped relative to the straight part. The slightly arc-shaped part can be used to clamp and stop bleeding of internal hemorrhoids of mixed hemorrhoids without affecting the use of the peeling part, thereby ensuring the normal function of the device.

[0016] The thickness of the hemostatic surface is 1.5-2 mm, and the thickness of the peeling surface is 0.3-1.2 mm.

[0017] This technical solution allows the thickness of the hemostatic and peeling surfaces to be set, ensuring their proper function while minimizing the peeling surface's thickness. The thinner the peeling surface, the thinner the blade, making it sharper when cutting the external hemorrhoids of mixed hemorrhoids. A thicker hemostatic surface reduces the clamping pressure exerted by the surface on the base of the mixed hemorrhoids, minimizing damage to the intestinal mucosa. Furthermore, a thinner peeling surface reduces the use of manufacturing materials, reducing costs.

[0018] The hemostatic surface includes a plurality of clamping teeth, the stripping surface includes a blade, the clamping teeth are blunt teeth, and the blade length of the blade is 0.5-1.5 mm.

[0019] This technical solution ensures the stability of the clamping teeth when clamping mixed and internal hemorrhoids, while also minimizing damage to the venous masses and facilitating subsequent ligation. The blade length is 0.5-1.5mm, which can be combined with the thickness of the peeling surface to enhance the sharpness of the blade and thus improve cutting accuracy.

[0020] Each of the scissor heads comprises a first part and a second part which are rotatable relative to each other, the hemostatic surface is arranged on the first part, the stripping surface is arranged on the second part, and a second locking device is arranged on the second part.

[0021] After adopting this technical solution, the scissors head is divided into two parts, the upper end surface being the first part and the lower end surface being the second part. The hemostatic surface is arranged in the first part and the stripping surface is arranged in the second part, thereby separating the hemostatic surface and the stripping surface. At the same time, a second locking device is provided to lock the stripping surface, so that the stripping part is closed and does not open and close simultaneously with the opening of the hemostatic part. When performing external stripping and internal ligation on some large mixed hemorrhoids, that is, clamping and hemostasis of internal hemorrhoids, the internal hemorrhoids will be placed in the gap between the hemostatic part and the second part near the hemostatic part, and the stripping part will not clamp the internal hemorrhoids, preventing the stripping surface from cutting the internal hemorrhoids, thereby ensuring the safety of the operation.

[0022] Wherein, the second locking device includes a fixing plate sleeved on the outside of the second part, the fixing plate is a concave structure, and the fixing plate is a telescopic structure.

[0023] After adopting this technical solution, the two second parts can be clamped and fixed by the extension and contraction of the fixing plate, so that the second parts are closed and will not open and close at the same time as the first parts. Therefore, when clamping internal hemorrhoids, larger internal hemorrhoids can be accommodated and protected through the gap between the hemostatic part and the second part close to the hemostatic part, thereby ensuring the safety of the operation.

[0024] The concave structure allows the fixing plate to be attached to the second portion. This connection and installation method is relatively simple. For mixed hemorrhoids of average size, there is no need to limit the position between the two second portions to protect oversized internal hemorrhoids. In this case, the fixing plate can be removed. If the mixed hemorrhoid is larger and requires protection, the fixing plate can be installed. Therefore, the provision of the second locking device increases the protection of larger mixed hemorrhoids, enhancing the practicality and flexibility of the device.

[0025] The extension length of the fixing plate is controlled by a control device, and the control device includes a control button arranged on the scissor body.

[0026] After adopting this technical solution, the fixing plate is controlled by the control device, which can simplify the difficulty of locking the second part, thereby simplifying the difficulty of operating the device and making the device easy to operate.

[0027] Wherein, the scissors body includes a scissors body, the scissors body includes a scissors ring, and a first locking device is provided on the scissors body.

[0028] With this technical solution, the shear rings can be used to coordinate with the doctor's fingers, allowing the scissors to be held. The first locking device can secure the position of the hemostatic surface, i.e., the degree of opening and closing of the hemostatic surface, when clamping mixed hemorrhoidal venous clusters (internal hemorrhoids) to stop bleeding, thus ensuring the stability of the clamping and hemostasis, and thus ensuring the ligation effect.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] (1) By using a hemostatic surface and a peeling surface, the hemostatic and peeling functions are combined into one device, realizing the conversion of peeling and hemostatic functions. This eliminates the need to repeatedly use hemostatic forceps and peeling scissors during surgery, making it more convenient for doctors to use the device. This can improve surgical efficiency and reduce surgical time.

[0031] (2) The structure in which the hemostatic surface is arranged on the inner side of the curved structure and the stripping surface is arranged on the outer side of the curved structure is adopted. This structure not only cooperates with the curved structure of the anorectal itself to more easily clamp the internal hemorrhoids and stop bleeding, but also protects the non-surgical part when cutting the stripping surface, ensuring the safety of the operation. At the same time, the width of the curved portion can be smaller than the width of the straight portion, making the end size of the curved portion smaller. When cutting the external hemorrhoids through the stripping portion of the curved portion, the cutting accuracy of the external hemorrhoids can be improved.

[0032] (3) The use of blunt teeth can not only ensure the stability of clamping, but also reduce the damage to the venous mass, making it easier to tie the vein. The thickness of the blade is combined with the thickness of the peeling surface to improve the sharpness of the blade, thereby increasing the speed of cutting.

[0033] (4) The hemostatic surface and the peeling surface are separated by the first part, the second part, and the second locking device, and the peeling surface is locked by the second locking device. When stopping bleeding, the internal hemorrhoids of mixed hemorrhoids of larger size will be placed in the gap between the second part and the second part near the hemostatic part, and the internal hemorrhoids will not be clamped, thereby avoiding the peeling surface from cutting the internal hemorrhoids and ensuring the safety of the operation.

[0034] (5) The first locking device can be used to fix the position of the hemostatic surface when clamping the mixed hemorrhoidal venous cluster (internal hemorrhoids) to stop bleeding, thereby ensuring the stability of the clamping hemostasis and thus ensuring the ligation effect.

[0047] The following combination Figure 1-Figure 7 The present invention is described in detail.

[0048] Example 1

[0049] An anorectal hemostasis and stripping device, such as Figure 1 and Figure 3 As shown, it includes two rotatably connected scissor bodies 1, each of which includes a scissor head 104, and the upper and lower end faces of each scissor head 104 are bent inward and extend toward the direction close to the other scissor head 104. The two ends of each scissor head 104 extending inward are respectively provided with a hemostatic surface 2 and a peeling surface 3, and the two hemostatic surfaces 2 are arranged opposite to each other to form a hemostatic part, and the two peeling surfaces 3 are arranged opposite to each other to form a peeling part.

[0050] In this embodiment, the scissors body 1 is made of stainless steel, which has high hardness, corrosion resistance, good elasticity, and is easy to clean and disinfect.

[0051] In this embodiment, the two scissor bodies 1 are rotatably connected by a joint 103. The joint 103 is similar in structure to the conventional mosquito-type hemostatic forceps. Specifically, a hinge rod is provided within the joint, and the two hinge rods enable the scissor bodies 1 to rotate relative to each other. This will not be described in detail here. In other embodiments, a conventional scissor structure may be used, such as by providing a hinge rod at a certain position of the scissor body 1 that passes through the two scissor bodies 1, and enabling the rotation of the two scissor bodies 1 via the hinge rod.

[0052] The upper and lower end surfaces of the scissors head 104 are extended (equivalent to providing a hollow structure in the scissors head 104, and providing a hemostatic surface 2 and a stripping surface 3 at both ends of the hollow structure), and a hemostatic surface 2 and a stripping surface 3 are provided on the two ends of the extension, respectively, to form a hemostatic part and a stripping part together with the hemostatic surface 2 and the stripping surface 3 of the other scissors head 104, respectively. The hemostatic part and the stripping part are arranged relative to each other at this time, that is, the hemostatic part and the stripping part are provided on the upper and lower end surfaces of the scissors body 1, respectively. The doctor can adopt the method of moving away-turning the wrist-re-clamping according to the progress of the external stripping and internal ligation operation of mixed hemorrhoids to realize the conversion of the stripping function and the hemostatic function, without having to repeatedly pick up and use the hemostatic forceps and the stripping shears alternately during the operation, so that it is more convenient for the doctor to use the device.

[0053] At the same time, since the use of this device does not require repeated replacement of hemostatic forceps and stripping scissors, doctors can also improve the efficiency of the operation and reduce the operation time when performing external stripping and internal ligation of mixed hemorrhoids using this device.

[0054] The upper and lower end surfaces of the scissor head 104 extend toward the other scissor head 104, and a hemostatic surface 2 and a peeling surface 3 are respectively provided on the extended parts. This arrangement creates a gap between the hemostatic surface 2 and the peeling surface 3. This gap can ensure the normal use of the hemostatic surface 2 and the peeling surface 3, so that the hemostatic part and the peeling part of the device can be used normally without interfering with each other, thereby improving the doctor's experience in using the device.

[0055] In this embodiment, the scissors head 104 includes a straight portion and a curved portion connected to the straight portion, the curved portion is bent upward, and the straight portion and the curved portion together constitute the curved structure of the scissors head 104, the hemostatic portion is arranged on the inner side of the curved structure of the scissors head 104, and the stripping portion is arranged on the outer side of the curved structure of the scissors head 104.

[0056] The arrangement of the curved portion and the straight portion changes the overall shape of the scissor head 104 into a curved shape with a slightly arc-shaped front end. This curved shape can cooperate with the curved shape structure of the anorectal. When the scissor head 104 is extended into the anorectal through the anus, the curved shape of the front end of the scissor head 104 can better fit with the anorectal wall, clamping the hemorrhoids on the anorectal wall and improving the stability of clamping the hemorrhoids on the anorectal wall.

[0057] The arrangement of arranging the hemostatic portion on the inner side of the curved structure and the stripping portion on the outer side of the curved structure facilitates the cutting of mixed hemorrhoids by the stripping portion. Since the front end of the scissor head 104 is a curved portion, the curved portion will not directly contact other intestinal walls that do not need to be cut, thereby preventing damage to the intestinal walls that do not need to be cut, thereby ensuring safety during the operation. When the stripping portion of the curved portion is used to cut and peel off an external hemorrhoid, the blade of the scissor head 104 on the curved portion can better adjust the angle to fit the mixed hemorrhoid compared to the blade of the scissor head 104 on the straight portion. The doctor can better control the force and angle when using the scissor head 104, thereby making the cutting of mixed hemorrhoids more precise and improving the cutting accuracy of the mixed hemorrhoids.

[0058] In this embodiment, the length of the scissors body 1 is 15-18 cm, and the thickness of the scissors head 104 is 3-5 cm, the length is 5-6 cm, and the width is 0.5-1.5 cm.

[0059] In other embodiments, the width of the curved portion can be set to be 0.1 cm smaller than the width of the straight portion, so that the width of the curved portion is smaller than that of the straight portion, which allows for more precise operation.

[0060] In this embodiment, Figure 1 As shown in the figure, the length of the scissors body 1 and the length and width of the scissors head 104 refer to the height and width of the entire scissors body 1 obtained from the perspective of the figure.

[0061] In this embodiment, Figure 2 As shown, the thickness of the scissor head 104 refers to the width of the scissor head 104 from the perspective of the figure.

[0062] In this embodiment, the length of the scissors body 1 is 18 cm, the thickness of the scissors head 104 is 4 cm, the length is 5 cm, and the width is 1 cm.

[0063] In this embodiment, the length of the curved portion is 1 cm, and the length of the straight portion is 4 cm.

[0064] The scissors body 1 is relatively long in overall length, the scissors head 104 is relatively narrow in width, and the thickness of the scissors head 104 is increased. First, by changing the thickness of the scissors head 104, the distance between the upper and lower end faces can be changed. By changing the distance between the upper and lower end faces, the position between the hemostatic portion and the stripping portion can be changed, thereby ensuring the normal use of the hemostatic portion and the stripping portion. Secondly, the scissors body 1 is relatively long and narrow in width, which matches the position of mixed external and internal hemorrhoids, and is suitable for the external stripping and internal ligation of mixed hemorrhoids, which can improve the doctor's feel when using this device for external stripping and internal ligation. At the same time, it can match the curved structure of the anorectal cavity, allowing the scissors body 1 to penetrate deep into the anorectal cavity, clamping and stopping bleeding of mixed hemorrhoids and internal hemorrhoids on the anorectal wall, and facilitating ligation. Finally, by increasing the thickness of the scissors head 104 and providing a hollow structure, the hemostatic surface 2 and the stripping surface 3 can be made to not interfere with each other during use, allowing the operation to proceed smoothly.

[0065] In this embodiment, the bending angle of the curved portion of the scissor head 104 is 15-30°.

[0066] In this embodiment, Figure 2 As shown in the figure, the bending angle of the bending portion refers to the angle formed by the vertical lines perpendicular to the two ends of the bending portion.

[0067] In this embodiment, the bending angle of the scissor head 104 is 20°.

[0068] The bending angle of the curved portion is limited so that the curved portion is only slightly arcuate relative to the straight portion. The slightly arcuate portion can clamp and stop bleeding of internal hemorrhoids of mixed hemorrhoids without affecting the use of the stripping portion, thereby ensuring the normal function of the device.

[0069] In this embodiment, the thickness of the hemostatic surface 2 is 1.5-2 mm, and the thickness of the peeling surface 3 is 0.3-1.2 mm.

[0070] In this embodiment, the thickness of the hemostatic surface 2 is 2 mm, and the thickness of the peeling surface 3 is 1 mm.

[0071] The thickness of the hemostatic surface 2 and the stripping surface 3 is set, and when ensuring the normal function of the hemostatic surface 2 and the stripping surface 3, the stripping surface 3 can be made thinner as much as possible. The thinner the stripping surface 3 is, the thinner the blade 301 is, and the sharper it is when the external hemorrhoid portion of the mixed hemorrhoid is cut. The thicker the thickness of the hemostatic surface 2 is, the more the clamping pressure of the hemostatic surface 2 on the mixed hemorrhoid hemorrhoid base can be reduced, and the damage to the intestinal mucosa can be reduced. Meanwhile, the thinner the thickness of the stripping surface 3 is, the more the use of the material can be reduced, and the effect of reducing costs is arranged.

[0072] In this embodiment, Figure 1-Figure 3As shown, the hemostatic surface 2 includes a plurality of clamping teeth 201, and the stripping surface 3 includes a blade 301. The clamping teeth 201 are blunt teeth, and the blade length of the blade 301 is 0.5-1.5 mm.

[0073] In this embodiment, 10 clamping teeth 201 are provided for every centimeter of the length of the scissor head 104 .

[0074] In this embodiment, the blade length of the blade 301 is 1.5 mm. The blades on the two scissor heads 104 are in opposite directions, so that the peeling surface 3 has the ability to cut and peel.

[0075] When clamping mixed hemorrhoids and internal hemorrhoids, the blunt teeth ensure stable clamping while reducing damage to the venous masses (internal hemorrhoids), facilitating subsequent ligation. The blade 301 has a blade length of 0.5-1.5 mm, which, combined with the thickness of the peeling surface 3, enhances the sharpness of the blade 301 and thus improves cutting accuracy.

[0076] In this embodiment, Figure 1-Figure 2 As shown, the scissor body 1 includes a scissor body 102 , the scissor body 102 includes a scissor ring 101 , and a first locking device is provided on the scissor body 1 .

[0077] The shear ring 101 is designed to cooperate with the doctor's fingers, allowing the scissors body 1 to be held by the fingers. The first locking device is provided to fix the position of the hemostatic surface 2, that is, the degree of opening and closing of the hemostatic surface 2, when the hemostatic surface 2 is clamping and hemostatically stopping mixed hemorrhoidal venous clusters (internal hemorrhoids), thereby ensuring the stability of the clamping and hemostasis, thereby ensuring the ligation effect.

[0078] In this embodiment, Figure 1-Figure 2 As shown, the first locking device is a ratchet 6 structure respectively provided on the two scissor bodies 102, and there are four ratchets 6. The two scissor bodies 1 are tightly hinged by the docking of the ratchets 6, thereby limiting the position of the hemostatic surface 2.

[0079] In this embodiment, the ratchet 6 structure is integrally formed with the shear body 1 by welding.

[0080] The specific method of use of the present invention is as follows:

[0081] Reference Figure 1-Figure 3When using the device, the doctor first observes the size of the internal hemorrhoids of the mixed hemorrhoids through an anoscope. Then, the doctor puts his thumb and ring finger through the two rings, and puts his index finger close to the scissors body 102 to abut against the scissors body 102. At this time, the doctor holds the tissue forceps in his left hand to lift the mixed hemorrhoid, and holds the device in his right hand, so that the peeling surface 3 is close to the top of the external hemorrhoid. A reverse "V"-shaped incision is made, and the skin is cut from the top of the external hemorrhoid to the outer edge of the external hemorrhoid. The external hemorrhoid tissue, including the external hemorrhoid vascular loop and fibrous hyperplasia tissue, is peeled off, and a part of the external hemorrhoid skin, i.e., a triangular skin flap, is retained. The external hemorrhoid part is completely peeled off to about 0.3 cm above the tooth line.

[0082] After the external hemorrhoids are treated, the doctor turns his wrist and clamps the venous mass of the internal hemorrhoids with the clamping teeth 201 of the hemostatic surface 2, double ligates the base of the internal hemorrhoids above the clamped area, removes part of the hemorrhoids, and completes the operation.

[0083] Example 2

[0084] This embodiment is basically the same as embodiment 1, except that: Figure 4-Figure 7 As shown, each of the scissor heads 104 includes a first portion 1041 and a second portion 1042 that can rotate relative to each other, the hemostatic surface 2 is arranged on the first portion 1041, the stripping surface 3 is arranged on the second portion 1042, and a second locking device is arranged on the second portion 1042.

[0085] The scissors head 104 is divided into two parts, the upper end face is the first part 1041, and the lower end face is the second part 1042. The hemostatic surface 2 is arranged on the first part 1041, and the stripping surface 3 is arranged on the second part 1042, thereby the hemostatic surface 2 and the stripping surface 3 are separated. At the same time, a second locking device is provided to lock the stripping surface 3, so that the stripping portion is closed and does not open and close simultaneously with the opening of the hemostatic portion. When performing external peeling and internal ligation on some larger mixed hemorrhoids, that is, when clamping hemorrhoids, the internal hemorrhoids will be placed in the gap between the hemostatic portion and the second part 1042 near the hemostatic portion, and the stripping portion will not clamp the internal hemorrhoids, thereby avoiding the stripping surface 3 from cutting the internal hemorrhoids, thereby ensuring the safety of the operation.

[0086] In this embodiment, Figure 4-Figure 5 and Figure 7 As shown, the second locking device includes a fixing plate 5 sleeved on the outside of the second portion 1042, the fixing plate 5 is a concave structure, and the fixing plate 5 is a telescopic structure.

[0087] In this embodiment, the first part 1041 and the scissor body 102 are integrally formed, and the second part 1042 is rotatably connected to the first part 1041 through a connecting rod 1043. The friction force of the contact surface between the second part 1042 and the first part 1041 is relatively large, and the contact between the first part 1041 and the second part is relatively stable, so that the second part 1042 can open and close synchronously with the opening and closing of the first part 1041, but does not affect the smoothness of the opening and closing of the first part 1041 and the second part 1042.

[0088] In other embodiments, in order to ensure that the first part 1041 and the second part 1042 can be opened and closed stably, a pin running through the first part 1041 and the second part 1042 can be provided. The first part 1041 and the second part 1042 can be opened and closed synchronously through the pin. When the first part 1041 and the second part 1042 do not need to be opened and closed synchronously, the pin can be directly removed.

[0089] In other embodiments, a first portion 1041 and a second portion 1042 may be provided on both sides of the scissor body 102, respectively. The first portion 1041 and the second portion 1042 are connected to the scissor body 102 via connecting rods 1043, respectively. The first portion 1041 and the second portion 1042 are connected to the scissor body 102 via a relatively large friction connection, thereby ensuring that the first portion 1041 and the second portion 1042 can open and close synchronously without affecting the smoothness of opening and closing. In this case, a second locking device may be provided on the first portion 1041, or on both the first portion 1041 and the second portion 1042, so that either the first portion 1041 or the second portion 1042 can be locked adaptively according to the surgical situation.

[0090] In this embodiment, the second portion 1042 is provided with an arcuate edge on a side close to the joint 103 to ensure that the second portion 1042 can rotate relative to the first portion 1041. In other embodiments, the length of the second portion 1042 can be set to be smaller than the length of the first portion 1041, so that the second portion 1042 can also rotate smoothly relative to the first portion 1041.

[0091] In this embodiment, Figure 7 As shown, the surface of the connecting rod 1043 is smooth, and the connecting rod 1043 is arranged near the joint 103. In this way, when the first part 1041 is opened and the second part 1042 is closed, the second part 1042 can rotate around the connecting rod 1043, so that the first part 1041 can be opened, while the second part 1042 will not open under the clamping action of the fixing plate 5. Because the connecting rod 1043 is arranged near the joint 103, it will not bend the connecting rod 1043, which will affect the use of the connecting rod 1043. It is sufficient for the second part 1042 to rotate around the connecting rod 1043 as the center, without causing the connecting rods 1043 to be misaligned, resulting in the connecting rod 1043 locking the position between the first part 1041 and the second part 1042.

[0092] In other embodiments, the connecting rod 1043 may not be provided between the first part 1041 and the second part 1042. It is only necessary to increase the friction between the contact surfaces of the first part 1041 and the second part 1042, such as by providing anti-slip grooves between the two contact surfaces (providing multiple oblique lines in different directions on the two surfaces of the metal in contact with each other, and achieving the anti-slip purpose through the friction between the oblique lines). This also allows the first part 1041 and the second part 1042 to be opened and closed at the same time when they need to be opened and closed at the same time, and the second part 1042 to be locked by the second locking device when they do not need to be opened and closed at the same time.

[0093] In this embodiment, Figure 7 As shown, the bottom plate of the fixed plate 5 includes a telescopic motherboard 502 and a telescopic sub-plate 501 that is sleeved within the telescopic motherboard 502. The telescopic sub-plate 501 and the telescopic motherboard 502 are connected by a telescopic rod 503. The telescopic rod 503 is electrically connected to a control motor 504, which is electrically connected to a receiving portion of a wireless signal transmission device. In other embodiments, the telescopic length of the fixed plate 5 can also be manually controlled. For example, using the telescopic structure of an umbrella main pole, elastic bumps are provided on the telescopic sub-plate 501, and positioning holes are provided on the telescopic motherboard 502 to cooperate with the elastic bumps. When the doctor manually pinches the telescopic sub-plate 501 to retract it to a corresponding position, the elastic bumps extend from the corresponding positioning holes, limiting the length between the telescopic sub-plate 501 and the telescopic motherboard 502, closing the second portion 1042 and disabling the peeling portion.

[0094] In this embodiment, the telescopic rod 503 is an electric telescopic rod, and the control button 4 controls the retraction of the telescopic rod 503. The electric telescopic rod can be manually controlled to retract when it is not powered on, that is, when the first part 1041 and the second part 1042 need to be opened and closed at the same time, the fixed plate 5 can automatically retract with the opening and closing of the scissor head 104 of the device. Because the fixed plate 5 is arranged on the side close to the joint 103, when the scissor head 104 opens and closes, the overall retractable range of the fixed plate 5 is small, which is equivalent to linear retraction. The telescopic rod 503 will not be deformed during this retraction. When only the hemostatic part needs to be opened and closed, it is only necessary to press and hold the control button 4 to retract the electric telescopic rod. The retraction and extension of the electric telescopic rod is a prior art, and is the same as the retractable principle and structure of electric tables and chairs. Both include a sub-rod and a mother rod, and the height or length is adjusted by electrically controlling the retraction and extension of the sub-rod in the mother rod.

[0095] In this embodiment, the telescopic motherboard 502 is provided with a sliding groove for accommodating the telescopic sub-board 501, and the telescopic sub-board 501 is placed in the sliding groove and a limit block is provided at the end thereof. Figure 7 As shown, the top of the telescopic sub-plate 501 is connected to the sub-rod of the telescopic rod by welding, and the main rod of the telescopic rod 503 is connected to the control motor 504 and then connected to the bottom of the slide.

[0096] In this embodiment, Figure 7 As shown, a fixing groove for installing the fixing plate 5 is provided on one side of the second part close to the joint 103, and a fixing protrusion that cooperates with the fixing groove is provided on the fixing plate 5. When in use, the fixing protrusion can be directly inserted into the fixing groove.

[0097] The two second parts 1042 can be clamped and fixed by the extension and contraction of the fixing plate 5, so that the second part 1042 is closed and will not open and close at the same time as the first part 1041. Therefore, when clamping the internal hemorrhoids, the gap between the hemostatic part and the second part 1042 near the hemostatic part can accommodate and protect the larger internal hemorrhoids, thereby ensuring the safety of the operation.

[0098] The concave structure allows the fixing plate 5 to be sleeved onto the second portion 1042. This connection and installation method is relatively simple. For mixed hemorrhoids of normal size, there is no need to limit the position between the two second portions 1042 to protect oversized internal hemorrhoids. In this case, the fixing plate 5 can be removed. If it is determined that the mixed hemorrhoid is large and requires protection, the fixing plate 5 can be installed. Therefore, the provision of the second locking device increases the protection of large mixed hemorrhoids, thereby enhancing the practicality and flexibility of the device.

[0099] In this embodiment, a suction cup is provided at the bottom of the control button 4 , and the control button 4 can be detachably connected to the scissor body 1 through the suction cup.

[0100] In this embodiment, the suction cup is connected to the bottom of the control button 4 by adhesion.

[0101] In this embodiment, a push switch is provided in the control button 4, and a wireless signal transmission device transmitting part is provided in the push switch. When the push button is pressed, the push button contacts the push switch, turning on the switch, and the wireless signal transmission device transmitting part receives the switch stimulation and starts to generate and transmit signals. The wireless signal transmission device receiving part in the fixed plate 5 receives the signal, and the wireless signal transmission device receiving part controls the control motor to rotate, driving the telescopic rod to contract, so that the two second parts 1042 are close to each other and the second part 1042 is locked.

[0102] Controlling the fixing plate 5 through the control device can simplify the difficulty of locking the second portion 1042, thereby simplifying the difficulty of operating the device and making the device easy to operate.

[0103] In this embodiment, the control button 4 is disposed on the scissor body 102 .

[0104] The control button 4 is arranged on the scissor body 102 and can cooperate with the doctor's posture of holding the hemostat. The index finger is placed on the scissor body 102 to maintain the stability of the device while pressing the control button 4.
