Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an anorectal hemostatic dissection device. Background Art

[0002] Hemostatic forceps and dissection scissors are commonly used medical devices in surgeries. Hemostatic forceps are mainly used to clamp blood vessels or tissues to stop blood flow, providing a clear field of view for doctors. They are shaped like a slender pair of pliers, with fine serrations at the front end for clamping blood vessels and tissues, and a locking structure at the rear end that can fix the opening and closing degree of the forceps. The cooperation of the serrations and the locking structure can stably clamp the blood vessels. Dissection scissors are mainly used for dissecting and separating tissues, and are commonly used for dissecting loose tissues, such as normal anatomical spaces, relatively loose adhesions, and spaces outside the capsules of benign tumors or cysts. Dissection scissors are usually connected by two blades and an intermediate hinge.

[0003] However, during the operation, especially during the external dissection and internal ligation of mixed hemorrhoids in anorectal surgery, when performing the external dissection and internal ligation of mixed hemorrhoids, the patient needs to take the lithotomy position or the lateral position, with local disinfection, infiltration anesthesia or lumbar anesthesia, and the mixed hemorrhoids need to be fully exposed. A "V"-shaped skin incision is made in the external hemorrhoid part, and the subcutaneous venous plexus of the external hemorrhoid is bluntly dissected with a hemostatic forceps until 0.3 cm above the dentate line. Then, the dissected external hemorrhoid flap and the base of the internal hemorrhoid are clamped with a curved hemostatic forceps, and a "0"-shaped ligation is made through the center of the base of the internal hemorrhoid with a round needle and thick silk thread. The skin and venous plexus within the "V" shape are cut off, resulting in a radial wound in the anal area. Due to the rich blood vessels and nerves in the anal area, the complex and narrow structure of the operation area in anorectal surgery, and the fragile and capillary-rich tissues at the operation site, bleeding is extremely likely to occur. To prevent bleeding from affecting the doctor's field of view during the operation and thus affecting the progress of the operation, doctors need to repeatedly pick up and alternately use hemostatic forceps and dissection scissors during the operation for hemostasis and tissue dissection, which brings many inconveniences to the precise operation of doctors. Summary of the Invention

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

[0005] To solve the above-mentioned existing technical problems, the technical solution adopted by the present invention is as follows:

[0006] An anorectal hemostatic dissection device includes two rotatably connected scissors bodies. Each scissors body includes a scissor head. The upper and lower end faces of each scissor head are bent inward and extend towards the direction close to the other scissor head. The two ends of each scissor head extending inward are respectively provided with a hemostatic surface and a dissection surface, and the two hemostatic surfaces are oppositely arranged to form a hemostatic part, and the two dissection surfaces are oppositely arranged to form a dissection part.

[0007] After adopting this technical solution, the upper and lower end faces of the scissor head are extended, and a hemostatic surface and a stripping surface are respectively arranged at the two extended ends, forming a hemostatic part and a stripping part with the hemostatic surface and the stripping surface of the other scissor head respectively. At this time, the hemostatic part and the stripping part are arranged opposite to each other, that is, the hemostatic part and the stripping part are respectively arranged on the upper and lower end faces of the scissor body. The doctor can adopt the method of moving away - flipping the wrist - re - clamping according to the progress of the external stripping and internal ligation surgery for mixed hemorrhoids to realize the transformation between the stripping function and the hemostatic function, without constantly repeatedly taking and alternately using a hemostatic forceps and a stripping scissor during the operation. Therefore, it is more convenient for the doctor to use this device. At the same time, because there is no need to repeatedly take and replace the hemostatic forceps and the stripping scissor when using this device, the doctor can also improve the operation efficiency and reduce the operation time when performing the external stripping and internal ligation surgery for mixed hemorrhoids through this device.

[0008] The upper and lower end faces of the scissor head extend towards the other scissor head, and a hemostatic surface and a stripping surface are respectively arranged at the extended parts. This setting method makes there be a gap between the hemostatic surface and the stripping surface, and this gap can ensure the normal use of the hemostatic surface and the stripping surface, so that the hemostatic part and the stripping part of this device can be used normally without interference, improving the doctor's using feeling when using this device.

[0009] Among them, the scissor head includes a straight part and a bent part connected to the straight part. The bent part bends upwards. The straight part and the bent part together form a scissor head bending structure. The hemostatic part is arranged inside the scissor head bending structure, and the stripping part is arranged outside the scissor head bending structure.

[0010] After adopting this technical solution, the setting of the bent part and the straight part makes the overall shape of the scissor head change into a bent shape with a slightly arcuate front end. This bent shape can cooperate with the shape structure of the anorectal bend. When the scissor head extends into the anorectum through the anus, the bent shape at the front end of the scissor head can better fit with the anorectal intestinal wall, clamping the hemorrhoids on the anorectal intestinal wall, and improving the clamping stability of the hemorrhoids on the anorectal intestinal wall.

[0011] And the setting of arranging the hemostatic part inside the bending structure and the stripping part outside the bending structure is convenient for when the stripping part cuts the external hemorrhoids of the mixed hemorrhoids. Because the front end of the scissor head is the bent part, the bent part will not directly contact other intestinal walls that do not need to be cut, and thus will not cause harm to the intestinal walls that do not need to be cut, ensuring the safety during the operation. When cutting and stripping the external hemorrhoids through the stripping part of the bent part, because the scissor head blade body of the bent part can be more adjusted in angle to fit with the external hemorrhoids of the mixed hemorrhoids compared with the scissor head blade body of the straight part, the doctor can better grasp the strength and angle when using it. Therefore, when cutting the external hemorrhoids of the mixed hemorrhoids, it will also be more delicate, improving the cutting precision of the external hemorrhoids of the mixed hemorrhoids.

[0012] Among them, the length of the shear body is 15 - 18 cm, and the thickness of the scissor head is 3 - 5 cm, the length is 5 - 6 cm, and the width is 0.5 - 1.5 cm.

[0013] After adopting this technical solution, the overall length of the shear body is relatively long, the width of the scissor head is relatively narrow, and the thickness of the scissor head increases. First, by changing the thickness of the scissor 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 hemostasis part and the dissection part can be changed, so as to ensure the normal use of the hemostasis part and the dissection part. Secondly, the overall length of the shear body is relatively long and the width is relatively narrow, which matches the positions of the external hemorrhoids and internal hemorrhoids of the mixed hemorrhoids and is suitable for the external dissection and internal ligation of the mixed hemorrhoids, and can improve the doctor's feeling when using this device for external dissection and internal ligation. At the same time, it can cooperate with the curved structure of the anus and rectum, so that the shear body can penetrate deep into the anus and rectum to clamp and stop bleeding the internal hemorrhoids of the mixed hemorrhoids on the intestinal wall of the anus and rectum, which is convenient for ligation. Finally, by increasing the thickness of the scissor head and setting a hollow structure, the hemostasis surface and the dissection surface can not interfere with each other during use, and the operation can proceed smoothly.

[0014] Among them, the bending angle of the bending part of the scissor head is 15 - 30°.

[0015] After adopting this technical solution, by limiting the bending angle of the bending part, the bending part is only a slightly arc-shaped relative to the straight part, which can not only clamp and stop bleeding the internal hemorrhoids of the mixed hemorrhoids through this slightly arc-shaped, but also does not affect the use of the dissection part, ensuring the normal function of this device.

[0016] Among them, the thickness of the hemostasis surface is 1.5 - 2 mm, and the thickness of the dissection surface is 0.3 - 1.2 mm.

[0017] After adopting this technical solution, by setting the thicknesses of the hemostasis surface and the dissection surface, while ensuring the normal functional use of the hemostasis surface and the dissection surface, the dissection surface can be made as thin as possible. The thinner the dissection surface, the thinner the blade will be, and it will be sharper when cutting the external hemorrhoids part of the mixed hemorrhoids. The thickness of the hemostasis surface is relatively thick, which can reduce the clamping pressure of the hemostasis surface on the base of the mixed hemorrhoid nucleus and reduce the damage to the intestinal mucosa. At the same time, the thinner the thickness of the dissection surface can also reduce the use of the production materials, with the effect of reducing costs.

[0018] Among them, several clamping teeth are included on the hemostasis surface, a blade is included on the dissection surface, the clamping teeth are blunt teeth, and the length of the blade surface of the blade is 0.5 - 1.5 mm.

[0019] After adopting this technical solution, when the blunt teeth clamp the internal hemorrhoids of the mixed hemorrhoids, it can not only ensure the clamping stability, but also reduce the damage to the venous mass, which is convenient for subsequent ligation. The length of the blade surface of the blade is 0.5 - 1.5 mm, which can be combined with the thickness of the dissection surface to improve the sharpness of the blade, thereby improving the accuracy during cutting.

[0020] Wherein, each of the scissor heads includes a first part and a second part that can rotate relative to each other. The hemostatic surface is provided on the first part, the peeling surface is provided on the second part, and a second locking device is provided on the second part.

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

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

[0023] After adopting this technical solution, the two second parts can be clamped and fixed by the telescoping of the fixing plate, so that the second part is closed and will not open and close simultaneously with the first part. Furthermore, when clamping the internal hemorrhoids, the large-sized internal hemorrhoids can be accommodated and protected through the gap between the hemostatic part and the second part close to the hemostatic part, ensuring the safety of the operation.

[0024] The setting of the concave structure can sleeved the fixing plate on the second part. This connection and installation method is relatively simple. For general-sized mixed hemorrhoids, it is not necessary to protect large-sized internal hemorrhoids by limiting the position between the two second parts. At this time, the fixing plate can be removed, and when it is determined that the mixed hemorrhoids are large-sized and need to protect the internal hemorrhoids, the fixing plate can be installed. Therefore, the setting of the second locking device increases the ability to protect large-sized mixed hemorrhoids and improves the practicability and flexibility of this device.

[0025] Wherein, the telescopic length of the fixing plate is controlled by a control device, and the control device includes a control button provided on the scissor body.

[0026] After adopting this technical solution, controlling the fixing plate through the control device can simplify the locking difficulty of the second part, thereby simplifying the operation difficulty of this device and making this device easy to operate.

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

[0028] After adopting this technical solution, the setting of the cutting ring can cooperate with the doctor's finger, and the cutting body can be held by the finger. The setting of the first locking device can fix the position of the hemostatic surface, that is, fix the opening and closing degree of the hemostatic surface, when clamping and stopping bleeding of the mixed hemorrhoid venous mass (internal hemorrhoid) on the hemostatic surface, ensuring the stability of the clamping and stopping bleeding, and thus ensuring the ligation effect.

[0029] To sum up, due to adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0030] (1) By adopting a hemostatic surface, a stripping surface, etc., the hemostatic function and the stripping function are combined into one device, realizing the transformation between the stripping function and the hemostatic function, without constantly repeatedly taking and using a hemostatic forceps and a stripping scissors during the operation. Therefore, it is more convenient for the doctor to use this device, which can improve the operation efficiency and reduce the operation time.

[0031] (2) By adopting a 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, it not only cooperates with the curved structure of the anorectal itself to more easily clamp the internal hemorrhoid and stop bleeding of the internal hemorrhoid, but also can protect the non-operative part during the cutting of the stripping surface, ensuring the safety of the operation. At the same time, the width of the curved part can be smaller than the width of the straight part, making the end size of the curved part smaller. When cutting the external hemorrhoid through the stripping part of the curved part, the cutting accuracy of the external hemorrhoid can be improved.

[0032] (3) By adopting blunt teeth, etc., it can not only ensure the stability of the clamping, but also reduce the damage to the venous mass, facilitating subsequent ligation. The combination of the thickness of the blade and the stripping surface improves the sharpness of the blade, thereby increasing the cutting speed.

[0033] (4) By adopting a first part, a second part and a second locking device, etc., the hemostatic surface and the stripping surface are separated, and the second locking device can lock the stripping surface. During hemostasis, the internal hemorrhoid of the larger-sized mixed hemorrhoid will be placed in the gap between the second part and the second part close to the hemostatic part, without clamping the internal hemorrhoid, avoiding the cutting of the internal hemorrhoid by the stripping surface, and ensuring the safety of the operation.

[0034] (5) By adopting a first locking device, etc., when clamping and stopping bleeding of the mixed hemorrhoid venous mass (internal hemorrhoid) on the hemostatic surface, the position of the hemostatic surface can be fixed, ensuring the stability of the clamping and stopping bleeding, and thus ensuring the ligation effect.

[0047] The following will Figures 1-7 describe the present invention in detail.

[0048] Embodiment 1

[0049] An anorectal hemostatic dissection device, as Figure 1 and Figure 3 shown, includes two rotatably connected scissors bodies 1. Each of the scissors bodies 1 includes a scissor head 104. The upper and lower end faces of each scissor head 104 are bent inward and extend towards the direction of the other scissor head 104. At both ends of each scissor head 104 extending inward, a hemostatic surface 2 and a dissection surface 3 are respectively arranged, and the two hemostatic surfaces 2 are oppositely arranged to form a hemostatic part, and the two dissection surfaces 3 are oppositely arranged to form a dissection 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 scissors bodies 1 are rotatably connected through a joint 103. The joint 103 has the same joint structure as that of a mosquito hemostat in the prior art and is prior art. Specifically, a hinge rod is arranged inside the joint, and the two scissors bodies 1 are rotated relative to each other through the two hinge rods, and no more description will be given here. In other embodiments, a common scissor structure can also be adopted, such as arranging a hinge rod penetrating through the two scissors bodies 1 at a certain part of the scissors body 1, and the two scissors bodies 1 can be rotated through the hinge rod.

[0052] Extend the upper and lower end faces of the scissor head 104 (equivalent to having a hollow structure in the scissor head 104, with a hemostatic surface 2 and a dissection surface 3 provided at both ends of the hollow structure), and respectively set the hemostatic surface 2 and the dissection surface 3 on the extended two ends, forming a hemostatic part and a dissection part with the hemostatic surface 2 and the dissection surface 3 of another scissor head 104 respectively. At this time, the hemostatic part and the dissection part are arranged oppositely, that is, the hemostatic part and the dissection part are respectively set on the upper and lower end faces of the scissor body 1. The doctor can adopt the way of moving away - flipping the wrist - re - clamping according to the progress of the external dissection and internal ligation operation of the mixed hemorrhoid to realize the transformation between the dissection function and the hemostasis function, without constantly taking and alternately using a hemostat and a dissection scissor during the operation. Therefore, it is more convenient for the doctor to use this device.

[0053] At the same time, because there is no need to repeatedly take and replace the hemostat and the dissection scissor when using this device, the doctor can also improve the operation efficiency and reduce the operation time when performing the external dissection and internal ligation of the mixed hemorrhoid through this device.

[0054] The upper and lower end faces of the scissor head 104 extend towards another scissor head 104, and the hemostatic surface 2 and the dissection surface 3 are respectively set on the extended parts. This setting method makes there be a gap between the hemostatic surface 2 and the dissection surface 3. This gap can ensure the normal use of the hemostatic surface 2 and the dissection surface 3, so that the hemostatic part and the dissection part of this device can be used normally without interference, improving the doctor's sense of use of this device.

[0055] In this embodiment, the scissor head 104 includes a straight part and a bent part connected to the straight part. The bent part bends upwards. The straight part and the bent part together form the bent structure of the scissor head 104. The hemostatic part is arranged on the inner side of the bent structure of the scissor head 104, and the dissection part is arranged on the outer side of the bent structure of the scissor head 104.

[0056] The setting of the bent part and the straight part makes the overall shape of the scissor head 104 become a bent shape with a slightly arcuate front end. This bent shape can cooperate with the shape structure of the anorectum. When the scissor head 104 extends into the anorectum through the anus, the bent shape at the front end of the scissor head 104 can better fit the anorectal intestinal wall, clamp the hemorrhoids on the anorectal intestinal wall, and improve the stability of clamping the hemorrhoids on the anorectal intestinal wall.

[0057] By arranging the hemostatic part inside the bending structure and the peeling part outside the bending structure, it is convenient to cut the external hemorrhoids of the mixed hemorrhoids through the peeling part. Since the front end of the scissor head 104 is a bending part, the bending part will not directly contact other intestinal walls that do not need to be cut, so it will not cause harm to the intestinal walls that do not need to be cut, ensuring the safety during the operation. When cutting and peeling the external hemorrhoids through the peeling part of the bending part, since the blade body of the scissor head 104 of the bending part can fit the external hemorrhoids of the mixed hemorrhoids in a way of adjusting the angle better than the blade body of the scissor head 104 of the straight part, the doctor can better grasp the strength and angle during use. Therefore, when cutting the external hemorrhoids of the mixed hemorrhoids, it will be more delicate, improving the cutting accuracy of the external hemorrhoids of the mixed hemorrhoids.

[0058] In this embodiment, the length of the scissor body 1 is 15 - 18 cm, and the thickness of the scissor 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 bending part can also be set 0.1 cm less than the width of the straight part, making the width of the bending part smaller than that of the straight part, and it will be more delicate during operation.

[0060] In this embodiment, as Figure 1 shown, the length of the scissor body 1, the length and width of the scissor head 104 refer to the overall height, width, etc. of the scissor body 1 obtained from the perspective of this figure.

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

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

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

[0064] The overall length of the scissors body 1 is relatively long, the width of the scissor head 104 is relatively narrow, and the thickness of the scissor head 104 is increased. First, by changing the thickness of the scissor 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 part and the dissection part can be changed, so as to ensure the normal use of the hemostatic part and the dissection part. Secondly, the overall length of the scissors body 1 is relatively long and the width is relatively narrow, which is matched with the positions of the external and internal hemorrhoids of the mixed hemorrhoids and is suitable for the external dissection and internal ligation of the mixed hemorrhoids, which can improve the doctor's feeling when using this device for external dissection and internal ligation. At the same time, it can be matched with the curved structure of the anus and rectum, so that the scissors body 1 can penetrate deep into the anus and rectum to clamp and stop bleeding the internal hemorrhoids of the mixed hemorrhoids on the intestinal wall of the anus and rectum, which is convenient for ligation. Finally, by increasing the thickness of the scissor head 104 and setting a hollow structure, the hemostatic surface 2 and the dissection surface 3 can not interfere with each other during use, and the operation can proceed smoothly.

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

[0066] In this embodiment, as Figure 2 shown, the bending angle of the bending part refers to the angle formed by the perpendicular lines perpendicular to both ends of the bending part.

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

[0068] Limiting the bending angle of the bending part makes the bending part only slightly arc-shaped relative to the straight part. It can not only clamp and stop bleeding the internal hemorrhoids of the mixed hemorrhoids through this slight arc shape, but also does not affect the use of the dissection part, ensuring the normal function of this device.

[0069] In this embodiment, the thickness of the hemostatic surface 2 is 1.5 - 2 mm, and the thickness of the dissection 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 dissection surface 3 is 1 mm.

[0071] Setting the thicknesses of the hemostatic surface 2 and the dissection surface 3 can, while ensuring the normal functional use of the hemostatic surface 2 and the dissection surface 3, make the dissection surface 3 as thin as possible. The thinner the dissection surface 3, the thinner the cutting edge 301 will be, and it will be sharper when cutting the external hemorrhoid part of the mixed hemorrhoids. And the hemostatic surface 2 has a relatively thick thickness, which can reduce the clamping pressure of the hemostatic surface 2 on the base of the mixed hemorrhoid nucleus and can reduce the damage to the intestinal mucosa. At the same time, the thinner the thickness of the dissection surface 3 can also reduce the use of production materials, with the effect of reducing costs.

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

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

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

[0075] When the blunt teeth clamp the internal hemorrhoids of the mixed hemorrhoids, it can not only ensure the stability of the clamping, but also reduce the damage to the venous mass (internal hemorrhoids), facilitating subsequent ligation. The blade surface length of the blade 301 is 0.5 - 1.5 mm, which can be combined with the thickness of the peeling surface 3 to enhance the sharpness of the blade 301, thereby improving the accuracy during cutting.

[0076] In this embodiment, as Figures 1-2 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 setting of the scissor ring 101 can cooperate with the doctor's finger to hold the scissor body 1 by the finger. The setting of the first locking device can fix the position of the hemostatic surface 2, that is, fix the opening and closing degree of the hemostatic surface 2, when the hemostatic surface 2 clamps and stops bleeding the venous mass (internal hemorrhoids) of the mixed hemorrhoids, ensuring the stability of the clamping and hemostasis, and thus ensuring the ligation effect.

[0078] In this embodiment, as Figures 1-2 shown, the first locking device is a ratchet 6 structure respectively provided on the two scissor bodies 102. There are 4 ratchets 6, and through the docking of the ratchets 6, the two scissor bodies 1 are tightly hinged to limit the position of the hemostatic surface 2.

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

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

[0081] Refer to Figures 1-3, when using this device, first observe the size of the internal hemorrhoids of the mixed hemorrhoids through an anoscope. Then, the doctor's thumb and ring finger pass through the two finger rings, and the index finger approaches the scissors body 102 and abuts against the scissors body 102. At this time, the doctor holds the tissue forceps in the left hand to lift the mixed hemorrhoids, and holds this device in the right hand, making the dissection surface 3 close to the top of the external hemorrhoids. Make an inverted "V" - shaped incision, cut the skin from the top of the external hemorrhoids to the outer edge of the external hemorrhoids, and dissect the external hemorrhoid tissue, including the external hemorrhoid vascular loop and fibrous hyperplasia tissue. Retain a part of the external hemorrhoid skin, namely the triangular skin flap, and completely dissect the external hemorrhoid part to about 0.3 cm above the dentate line.

[0082] After the external hemorrhoids are processed, the doctor then flips the wrist and clamps the venous mass of the internal hemorrhoid part through the clamping teeth 201 of the hemostatic surface 2, doubly ligate the base of the internal hemorrhoid above the clamped part, and excise part of the hemorrhoid nucleus to complete the operation.

[0083] Embodiment 2

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

[0085] The scissor head 104 is divided into upper and lower parts. The upper end surface is the first part 1041, and the lower end surface is the second part 1042. The hemostatic surface 2 is provided on the first part 1041, and the dissection surface 3 is provided on the second part 1042, so as to separate the hemostatic surface 2 and the dissection surface 3. At the same time, a second locking device is provided to lock the dissection surface 3, so that the dissection part is closed and does not open and close simultaneously with the opening and closing of the hemostatic part. When performing external dissection and internal ligation on some relatively large - sized mixed hemorrhoids, that is, when clamping and stopping bleeding for the internal hemorrhoids, the internal hemorrhoids will be placed in the gap between the hemostatic part and the part of the second part 1042 close to the hemostatic part, and the dissection part will not clamp the internal hemorrhoids, avoiding the dissection surface 3 from cutting the internal hemorrhoids and ensuring the safety of the operation.

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

[0087] In this embodiment, the first part 1041 is integrally formed with the body 102 of the scissors. The second part 1042 is rotatably connected to the first part 1041 through a connecting rod 1043. The frictional force between the contact surfaces of 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 open and close stably, a bolt passing through the first part 1041 and the second part 1042 can also be provided, so that the first part 1041 and the second part 1042 can open and close synchronously. When the first part 1041 and the second part 1042 do not need to open and close synchronously, the bolt can be directly removed.

[0089] In other embodiments, the first part 1041 and the second part 1042 can also be respectively provided on both sides of the body 102 of the scissors. The first part 1041 and the second part 1042 are respectively connected to the body 102 of the scissors through connecting rods 1043, and the first part 1041 and the second part 1042 are connected by a relatively large friction, so as to ensure that the first part 1041 and the second part 1042 can open and close synchronously without affecting the smoothness of the opening and closing. At this time, a second locking device can be provided on the first part 1041, or second locking devices can be provided on both the first part 1041 and the second part 1042, and the first part 1041 or the second part 1042 can be locked adaptively according to the surgical situation.

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

[0091] In this embodiment, as Figure 7 shown, the surface of the connecting rod 1043 is smooth, and the connecting rod 1043 is arranged at a position close to the joint 103. When the first part 1041 needs to be opened and the second part 1042 needs to be 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 be opened under the clamping action of the fixing plate 5. Also, because the connecting rod 1043 is arranged at a position close to the joint 103, the connecting rod 1043 will not be bent, affecting the use of the connecting rod 1043. Only the second part 1042 needs to rotate around the connecting rod 1043, and the connecting rods 1043 will not be misaligned, resulting in the connecting rod 1043 locking the positions 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. For example, anti-slip patterns are provided between the two contact surfaces (a plurality of diagonal lines with different orientations are provided on the two surfaces where metals are in contact with each other, and the anti-slip purpose can be achieved through the friction between the diagonal lines). In this way, when simultaneous opening and closing are required, the first part 1041 and the second part 1042 can be opened and closed simultaneously. When simultaneous opening and closing are not required, the second locking device is used to lock the second part 1042.

[0093] In this embodiment, as Figure 7 shown, the bottom plate of the fixed plate 5 includes a telescopic mother plate 502 and a telescopic son plate 501 sleeved in the telescopic mother plate 502. The telescopic son plate 501 and the telescopic mother plate 502 are connected by a telescopic rod 503. The telescopic rod 503 is electrically connected to a control motor 504, and the control motor 504 is electrically connected to a wireless signal transmission device receiving part. In other embodiments, the telescopic length of the fixed plate 5 can also be controlled manually. For example, the telescopic structure of the main rod of an umbrella is adopted. Elastic bumps are provided on the telescopic son plate 501, and positioning holes are provided on the telescopic mother plate 502 that cooperate with the elastic bumps. When the doctor pinches the telescopic son plate 501 and retracts it to the corresponding position, the elastic bumps protrude from the corresponding positioning holes to limit the length between the telescopic son plate 501 and the telescopic mother plate 502, so that the second part 1042 is closed and the peeling part does not function.

[0094] In this embodiment, the telescopic rod 503 is an electric telescopic rod, and the control button 4 controls the telescopic rod 503 to contract. The electric telescopic rod can be manually controlled to expand and contract when not powered on. That is, when the first part 1041 and the second part 1042 need to be opened and closed simultaneously, the fixed plate 5 can automatically expand and contract with the opening and closing of the scissors head 104 of the device. Because the fixed plate 5 is arranged on one side close to the joint 103, when the scissors head 104 opens and closes, the overall telescopic range of the fixed plate 5 is small, equivalent to linear expansion and contraction, and the telescopic rod 503 will not be deformed during this expansion and contraction. When only the hemostatic part needs to be opened and closed, it is only necessary to press the control button 4 to make the electric telescopic rod contract. The expansion and contraction of the electric telescopic rod are prior art, and have the same principle and structure as the expansion and contraction of an electric table and chair, both including a son rod and a mother rod, and the height or length is adjusted by electrically controlling the expansion and contraction of the son rod in the mother rod.

[0095] In this embodiment, a chute for accommodating the telescopic son plate 501 is provided in the telescopic mother plate 502. The telescopic son plate 501 is placed in the chute and a limiting block is provided at the end, as Figure 7 shown, the top of the telescopic son plate 501 is connected to the son rod of the telescopic rod by welding, and the mother rod of the telescopic rod 503 is connected to the control motor 504 and then connected to the bottom of the chute.

[0096] In this embodiment, as Figure 7 shown, a fixing groove for installing the fixing plate 5 is provided on one side of the second part close to the joint 103. A fixing protrusion cooperating with the fixing groove is provided on the fixing plate 5. During use, the fixing protrusion can be directly inserted into the fixing groove.

[0097] By the telescoping of the fixing plate 5, the two second parts 1042 can be clamped and fixed, so that the second part 1042 is closed and will not open and close simultaneously with the first part 1041. Thus, when clamping the internal hemorrhoids, the larger-sized internal hemorrhoids can be accommodated and protected through the gap between the hemostatic part and the second part 1042 close to the hemostatic part, ensuring the safety of the operation.

[0098] The concave structure can sleeved the fixing plate 5 on the second part 1042. This connection and installation method is relatively simple. For ordinary-sized mixed hemorrhoids, it is not necessary to protect the overly large internal hemorrhoids by limiting the position between the two second parts 1042. At this time, the fixing plate 5 can be removed. When it is determined that the size of the mixed hemorrhoids is large and the internal hemorrhoids need to be protected, the fixing plate 5 can be installed. Therefore, the setting of the second locking device increases the ability to protect the larger-sized mixed hemorrhoids, and thus increases the practicability and flexibility of this device.

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

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

[0101] In this embodiment, a push switch is provided inside the control button 4, and a wireless signal transmission device transmitting part is provided inside the push switch. When the push button is pressed, the push button contacts the push switch to turn on the switch. 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 fixing plate 5 receives this 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 approach each other to lock the second part 1042.

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

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

[0104] The control button 4 is arranged on the scissors body 102, which can cooperate with the doctor's posture of holding the hemostatic forceps. While placing the index finger on the scissors body 102 to maintain the stability of the device during use, it is convenient to press the control button 4.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
