Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrocoagulation hemostatic forceps technology, and in particular to miniature electrocoagulation hemostatic forceps for animal experimental surgery. Background Technology
[0002] Miniature electrocoagulation hemostatic forceps are instruments used in surgery for hemostasis of small blood vessels and coagulation of tissue. They consist of a forceps body, electrodes, an insulating layer and a handle. Their working principle is to connect to a high-frequency electrosurgical unit to generate a high-frequency current, which causes the tissue ions at the surgical site to vibrate and rub against each other to generate heat, resulting in water evaporation, protein denaturation and coagulation, sealing blood vessels to stop bleeding and reduce bleeding, and providing a clear field of vision to facilitate delicate surgical operations.
[0003] When using electrocoagulation hemostatic forceps, first perform preoperative instrument checks, patient preparation, and equipment connection and debugging. During the operation, after exposing the bleeding point by incising the tissue, clamp the bleeding point with the hemostatic forceps, turn on the switch to perform electrocoagulation hemostasis and observe the effect. After the operation, promptly turn off the power, clean and disinfect the instruments, and at the same time, provide good patient care and observation.
[0004] However, some existing electrocoagulation hemostatic forceps cannot flexibly and accurately adjust the length of the forceps according to the specific requirements of different surgical scenarios. When faced with the differentiated needs of different surgical scenarios, it is difficult to fully meet the surgeon's expectations for instrument adaptability and precise operation. Therefore, in order to address the above shortcomings, a miniature electrocoagulation hemostatic forceps for animal experimental surgery is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a miniature electrocoagulation hemostatic forceps for animal experimental surgery, which aims to improve the problem that some electrocoagulation hemostatic forceps in the prior art cannot effectively adjust their length.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A miniature electrocoagulation hemostatic forceps for animal testing includes two connecting rods. An extension rod is fixedly connected to the left side of each connecting rod. A sliding sleeve is slidably connected to the outside of each extension rod. An elastic component is provided inside each extension rod. A groove is formed on the left side of the inside of each extension rod. A hemisphere is fixedly connected to the bottom of the elastic component. Multiple slots are formed on the bottom side of the inside of the sliding sleeve. An outer forceps body is fixedly connected to the left side of one connecting rod, and an inner forceps body is fixedly connected to the left side of the other connecting rod. Protective components are provided on the left exterior of both the outer and inner forceps bodies.
[0008] As a further description of the above technical solution:
[0009] The elastic component includes a sliding disk, the outside of which is slidably connected to the inside of the extension rod, a sliding rod is fixedly connected to the bottom of the sliding disk, and a spring is sleeved on the outside of the sliding rod;
[0010] As a further description of the above technical solution:
[0011] The protective component includes two ceramic coatings, with the opposite sides of the two ceramic coatings fixedly connected to the outside of the outer clamp and the inner clamp respectively. Silicone rubber strips are fixedly connected to the upper and lower sides of the outer clamp and the inner clamp.
[0012] As a further description of the above technical solution:
[0013] A handle is fixedly connected to the right side of each of the two connecting rods, and a positioning tooth plate is fixedly connected to the adjacent side of each of the two handles;
[0014] As a further description of the above technical solution:
[0015] The outer side of the sliding disk is slidably connected to the inside of the sliding groove, and the outer side of the hemisphere is slidably connected to the inside of the slot.
[0016] As a further description of the above technical solution:
[0017] The outer side of the sliding rod is slidably connected to the inside of the extension rod, and the outer side of the hemisphere is slidably connected to the inside of the sliding sleeve;
[0018] As a further description of the above technical solution:
[0019] One end of the spring is fixedly connected to the bottom of the extension rod, and the other end of the spring is fixedly connected to the top of the hemisphere;
[0020] As a further description of the above technical solution:
[0021] The outer right side of the inner clamp body is slidably connected to the inner right side of the outer clamp body, and the bottom of one of the positioning teeth contacts the top of the other positioning teeth.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this invention, when the hemisphere is pressed, it slides into the sliding sleeve, causing the sliding disc to slide within the groove. This compresses the spring surrounding the sliding rod, storing elastic potential energy. Pulling the connecting rod then allows the extension rod to slide within the sliding sleeve, changing its length. When the hemisphere moves to the designated slot position, the spring releases its elastic potential energy, pushing the hemisphere back into place in the slot at the bottom of the sliding sleeve, thus locking the length of the hemostat. This allows the hemostat to flexibly adjust its length according to the needs of different surgical scenarios, facilitating its operation by the surgeon.
[0024] 2. In this invention, the extremely low coefficient of friction of ceramic material is utilized to significantly reduce friction between the electrocoagulation hemostat and the tissue, effectively preventing mechanical damage to blood vessels and other tissues during operation. Simultaneously, the silicone rubber strips fixedly connected to the upper and lower sides of the outer and inner clamps, thanks to the softness and elasticity of silicone rubber, further cushion the tissue when the hemostat grasps it, reducing compression and damage to the tissue. This makes the entire operation smoother, reduces traction and tearing of the tissue, maximizes tissue protection, and improves the safety of the surgical procedure. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a miniature electrocoagulation hemostatic forceps for animal experimental surgery, comprising two connecting rods 1. The connecting rods 1 are crucial connecting components of the entire hemostatic forceps, providing support and connection for other structures. Extension rods 2 are fixedly connected to the left side of each of the two connecting rods 1, allowing the length of the hemostatic forceps to be adjusted to suit different surgical scenarios. Sliding sleeves 3 are slidably connected to the outside of each of the two extension rods 2. An elastic component is provided inside the extension rod 2, and a groove 4 is formed on the left side of the inside of the extension rod 2. A hemisphere 8 is fixedly connected to the bottom of the elastic component, and the outside of the hemisphere 8 is slidably connected to the inside of the sliding sleeve 3. Multiple slots 9 are formed on the bottom side of the inside of the sliding sleeve 3, and the outside of the hemisphere 8 is slidably connected to the inside of the slots 9. An outer forceps body 10 is fixedly connected to the left side of one connecting rod 1, and an inner forceps body 11 is fixedly connected to the left side of the other connecting rod 1. The outer right side of the inner forceps body 11 is slidably connected to the inner right side of the outer forceps body 10. The inner forceps body 11 can flexibly open and close relative to the outer forceps body 10, enabling the clamping and releasing of tissue. Both the outer clamp 10 and the inner clamp 11 have protective components on their left outer sides.
[0034] Reference Figures 1 to 3 The elastic component includes a sliding disc 5, which is externally slidably connected to the inside of a groove 4. The sliding disc 5 can move stably up and down along the direction of the groove 4. The externally slidably connected to the inside of an extension rod 2, the bottom of which is fixedly connected to a sliding rod 6. The sliding rod 6 provides support and guidance for the spring 7, thereby stably transmitting the elastic force of the spring 7 and the external force during operation. The externally slidably connected to the inside of an extension rod 2, the sliding rod 6 is fitted with a spring 7. One end of the spring 7 is fixedly connected to the bottom of the extension rod 2, and the other end is fixedly connected to the top of a hemisphere 8. When the hemisphere 8 is pressed and the spring 7 is compressed, it can store elastic potential energy. When the hemisphere 8 moves to the designated slot 9, the spring 7 releases the elastic potential energy, pushing the hemisphere 8 to reset and lock into the slot 9, thereby locking the length of the hemostat.
[0035] Reference Figure 1 , Figure 4 and Figure 5The protective components include two ceramic coatings 14, with their distal ends fixedly connected to the exterior of the outer clamp body 10 and the inner clamp body 11, respectively. The ceramic coatings 14 cover their outer sides, effectively reducing friction between the electrocoagulation hemostat and tissue, thus preventing mechanical damage to blood vessels and other tissues during operation. Silicone rubber strips 15 are fixedly connected to the upper and lower sides of both the outer clamp body 10 and the inner clamp body 11. The silicone rubber further reduces compression and damage to tissues during operation.
[0036] Reference Figures 1 to 2 Each of the two connecting rods 1 has a handle 12 fixedly connected to its right side, allowing the surgeon to easily control the opening and closing force and direction of the hemostat. Positioning teeth 13 are fixedly connected to adjacent sides of the two handles 12, with the bottom of one positioning tooth 13 contacting the top of the other. The positioning teeth 13 provide stable positioning and fixation when the hemostat is closed. When the surgeon closes the hemostat to the appropriate position, the positioning teeth 13 interlock, preventing accidental opening or changes in closing force, thus ensuring the accuracy and stability of the surgical procedure.
[0037] Working principle: When the length of this hemostat needs to be extended, the hemisphere 8 can be pressed to slide into the sliding sleeve 3. At this time, the sliding plate 5 will slide inside the sliding groove 4, which will compress the spring 7. Then, the connecting rod 1 can be pulled to slide the extension rod 2 inside the sliding sleeve 3. When the hemisphere 8 moves to the designated slot 9, the elastic force of the spring 7 will cause the hemisphere 8 to return to its original position, which will then lock the hemisphere 8 into the bottom of the sliding sleeve 3. This allows the length of the hemostat to be adjusted. At the same time, the ceramic coating 14 and the silicone rubber strip 15 can effectively improve the safety of the hemostat during use, effectively reduce the friction between the electrocoagulation hemostat and the tissue, avoid mechanical damage to blood vessels and other tissues during operation, make the operation smoother, and reduce the pulling and tearing of tissues.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
