[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0025] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0026] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0027] In the following specific embodiments, the scissor-type surgical instrument can be any scissor-type structure required in surgical procedures. For example, the scissor-type surgical instrument can be a hemostat. For example, the scissor-type surgical instrument can also be an ultrasonic scissor. The structure and function of the scissor-type surgical instrument will be described by way of example below with reference to various embodiments.

[0028] In some embodiments, such as Figure 1 As shown, the scissor-type surgical instrument 10 includes a first part 100 and a second part 200. Two opposing ends are formed along the extending direction of the first part 100, with a first working part 110 and a first gripping part 120 respectively formed at each end. Two opposing ends are formed along the extending direction of the second part 200, with a second working part 210 and a second gripping part 220 respectively formed at each end. A tissue-holding pad is provided on the surface of the first working part 110 facing the second working part 210. The first part 100 and the second part 200 are rotatably connected, with the first working part 110 and the second working part 210 located on the same side of the connection position. Correspondingly, the first gripping part 120 and the second gripping part 220 are located on the same side of the connection position. This means that by gripping the first part 120 and the second gripping part 220 and rotating them around the connection position, the first gripping part 120 and the second gripping part 220... The first working part 110 and the second working part 210 can move closer or further apart, thereby enabling the scissor-type surgical instrument 10 to perform the corresponding functions. For example, when the scissor-type surgical instrument 10 is used as a hemostat, by bringing the first working part 110 and the second working part 210 closer together and clamping the patient's bleeding site, the blood flow is blocked by coagulating the blood vessel wall at the bleeding site, thereby achieving hemostasis. For example, when the scissor-type surgical instrument 10 is used as a cutting device, the lesion of the patient is cut away by bringing the first working part 110 and the second working part 210 closer together. Optionally, the opposing parts of the first working part 110 and the second working part 210 are provided with cutting blades, thereby enabling the cutting function. Optionally, the first working part 110 and the second working part 210 achieve the cutting function through ultrasonic vibration.

[0029] The second grip portion 220 includes a first grip cavity 221 and a second grip cavity 222, which are arranged along the extension of the second portion 200. The distance between the second grip cavity 222 and the second working portion 210 is greater than the distance between the first grip cavity 221 and the second working portion 210. The first grip portion 120 also has a third grip cavity 121. For example, in combination with... Figure 1 and Figure 2During use, at least the operator's middle and ring fingers are accommodated in the first grip cavity 221, the operator's thumb in the third grip cavity 121, and the operator's little finger in the second grip cavity 222. In this grip posture, when holding a scissor-type surgical instrument, a certain distance must exist between the little finger and ring finger to allow the little finger to relax. If the little finger, ring finger, and middle finger are accommodated in the same grip cavity, the squeezing force between the three fingers will increase, and the little finger will be in a state of tension for a long time. Prolonged gripping of this scissor-type surgical instrument can cause hand discomfort for the operator. If the little finger is suspended outside the grip cavity, it will prevent the little finger from exerting force, making it inconvenient for the operator to operate. Moreover, the little finger being suspended for a long time will also cause discomfort to the operator's hand. By setting the first grip cavity 221 and the second grip cavity 222, the operator's middle finger and ring finger can be located in the first grip cavity 221, and the little finger can be accommodated in the second grip cavity 222. Thus, while the little finger can be supported, there is also a certain distance between the little finger and the ring finger. This allows the little finger to participate in the exertion of force and also allows the little finger to be in a relaxed state, so that the operator's hand can still maintain a relatively comfortable state during long-term gripping.

[0030] This utility model provides a scissor-type surgical instrument. The scissor-type surgical instrument includes a first portion forming a first working part and a first gripping part at both ends, and a second portion forming a second working part and a second gripping part at both ends. The first portion and the second portion are rotatably connected, and the first working part and the second working part are located on the same side of the connection position. By gripping the first gripping part and the second gripping part, the first working part and the second gripping part can be moved closer to or further apart, thereby realizing the function of a scissor-type surgical instrument. The first gripping part includes a third gripping cavity, and the second gripping part includes a first gripping cavity and a second gripping cavity. Furthermore, the first gripping cavity and the second gripping cavity extend from the second portion... The gripping parts are arranged in the extending direction, and the distance between the second gripping cavity and the second working part is greater than the distance between the first gripping cavity and the second working part. During use, the operator's thumb is accommodated in the third gripping cavity, at least the middle and ring fingers are accommodated in the first gripping cavity, and the little finger is accommodated in the second gripping cavity. By setting separate first and second gripping cavities and using the independent second gripping cavity to accommodate the little finger, a certain distance can be maintained between the little finger and the ring finger while supporting the little finger. This allows the little finger to participate in the force exertion and to be in a relaxed state, thereby improving the operator's hand comfort during long-term gripping.

[0031] In some embodiments, such as Figure 1As shown, the second gripping cavity 222 has an opening 223, and the opening 223 faces away from the second working part 210. By setting the opening 223, the operator's little finger can more easily insert into the second gripping cavity 222. Moreover, since the opening faces away from the second working part 210, the little finger has less range of motion in that direction, so the little finger is less likely to come out of the second gripping cavity 222 during operation. The end of the second gripping part 220 has a first blocking wall 224. In the extension direction perpendicular to the second part 200, the first blocking wall 224 is located on the side of the second part 200 closer to the first part 100. It can be understood that the first blocking wall 224 protrudes from the first part 100. The outer surface of the portion forming the first grip cavity 222 is surrounded by a first blocking wall 224, which surrounds at least a portion of the second grip cavity 222. This allows the operator's little finger to apply force towards the first portion 100 by pressing the first blocking wall 224, so that the first working part 110 and the second working part 210 move closer to each other. It should be noted that the direction in which the first working part 110 and the second working part 210 move closer to each other is the main working direction of the scissor-type surgical instrument 10. In this direction, the user needs to apply greater force. By placing the first blocking wall 224 on the side closer to the first portion 100, it is easier for the operator's little finger to participate in applying force in this direction.

[0032] In some embodiments, such as Figure 3 As shown, the end of the second grip portion 220 also has a second blocking wall 225. In the extension direction perpendicular to the second portion 200, the first blocking wall 224 and the second blocking wall 225 are spaced apart, and the second blocking wall 225 is located on the side away from the first portion 100, so that the first blocking wall 224 and the second blocking wall 225 can form a second grip cavity 222 with an opening 223. By setting the second blocking wall 225, the little finger can also participate in the movement of the second portion 200 in the outward expansion direction, which makes it easier for the operator to exert force with their hand, and the little finger is less likely to slip.

[0033] In some embodiments, such as Figure 4As shown, the scissor-type surgical instrument 10 also includes a transducer 310 and a sterile protective sleeve 320. The transducer 310 is fixedly connected to the end of the second grip 220, and this end is located on the side away from the second working part 210. The transducer 310 can convert external electrical energy into ultrasonic vibrations, which can be transmitted to the first working part 110 and the second working part 210. This allows for easier removal of the patient's lesions through the ultrasonic vibrations of the first working part 110 and the second working part 210. The scissor-type surgical instrument 10 is a scissor-type ultrasonic surgical instrument; at the same time, the sterile protective sleeve 320 is fitted over the outside of the transducer 310, thereby isolating the transducer 310 from the external bacterial environment, so that the transducer 310 does not need to be sterilized before the next operation. Moreover, at least a part of the sterile protective sleeve 320 extends into the second grip cavity 220, that is, the second grip cavity 220 is not only used to accommodate the operator's little finger, but also used to help fix the sterile protective sleeve 320.

[0034] In some embodiments, such as Figure 4 As shown, the inner wall portion of the first blocking wall 224 that surrounds the inner wall forming the second gripping cavity 222 has a positioning groove 226. The end of the sterile protective sleeve 320 that extends into the second gripping cavity 222 extends into the positioning groove 226, thereby more reliably fixing the sterile protective sleeve 320 through the positioning groove 226; optionally, as Figure 4 As shown, along the extending direction of the second part 200, the positioning groove 226 is located at the end of the first blocking wall 224 near the second working part 210. With the little finger accommodated in the second receiving cavity 222, the gap between the little finger and ring finger generally positions the little finger away from the positioning groove 226. This allows for more reliable fixation of the sterile protective sleeve 320 while reducing the impact of the positioning groove 226 on the little finger. Optionally, such as... Figure 4 As shown, the end of the second part 200 also includes a positioning protrusion 230. In the extension direction perpendicular to the second part, the positioning protrusion 230 is located on the side of the second part 200 closer to the first part. That is, in this direction, the positioning protrusion 230 and the positioning groove 226 are located on both sides of the second part 200, so that the sterile protective sleeve 320 can be more reliably fixed at the same time by the positioning protrusion 230 and the positioning groove 226.

[0035] In some embodiments, such as Figure 1As shown, the outer surface of the second part 200 also includes an energy excitation button 400. The energy excitation button 400 is used to generate radio frequency ultrasonic vibrations in the first working part 110 and the second part 210 according to the user's pressing operation. For example, the vibration frequency of the radio frequency ultrasonic vibration is between 40 MHz and 63 MHz, thereby acting as a radio frequency ultrasonic scalpel. In the extension direction perpendicular to the second part 200, the energy excitation button 400 is located on the side of the second part 200 away from the first part 100, so that the operator's finger can press the energy excitation button 400, thereby facilitating the operator to trigger the radio frequency ultrasonic vibration of the working part. In the extension direction of the second part 200, the energy excitation button 400 is located on the side of the first grip cavity 221 closer to the second working part 210, that is, the energy excitation button 400 is closer to the operator's index finger. Since the index finger has a greater range of motion and is easier to exert force, setting the energy excitation button 400 in this position makes it easier for the operator to press the energy excitation button 400 with the index finger, thereby more conveniently triggering the radio frequency ultrasonic vibration of the working part.

[0036] Among them, such as Figure 5 As shown, the outer surface of the second part 200 includes an excitation surface 240. The area where the excitation surface 240 is located provides space for the installation of the energy excitation button 400. The energy excitation button 400 is installed in this area. Moreover, the energy excitation button 400 has a pressing surface 401 for pressing. The pressing surface 401 is parallel to the excitation surface 240. That is, the pressing surface 401 is slightly higher than the excitation surface 240 and has a shape that is approximately parallel to the excitation surface 240. This ensures that the pressing surface 401 does not put excessive pressure on the user's index finger, reduces the risk of the pressing surface 401 pressing against the hand, and further improves the user's hand comfort. Optionally, the energy excitation button 400 includes a hard rubber portion and a soft rubber portion. The hard rubber portion extends into the excitation surface 240, thereby enabling more reliable triggering of the radio frequency ultrasonic vibration of the working part by contacting the trigger area of ​​the control circuit board below the pressing surface 401. The soft rubber portion covers the outer surface of the hard rubber portion away from the excitation surface 240, thereby forming the pressing surface 401 of the energy excitation button 400, further reducing the risk of the pressing surface 401 being uncomfortable to the hand.

[0037] In some embodiments, such as Figure 5As shown, the energy adjustment button 400 includes a first button 410 and a second button 420, which are spaced apart. The two buttons are used to generate radio frequency ultrasonic vibrations of different amplitude intensities in the working part. For example, the first button 410 is used to trigger radio frequency ultrasonic vibrations of the working part at a first amplitude intensity, and the second button 420 is used to trigger radio frequency ultrasonic vibrations of the working part at a second amplitude intensity, where the first amplitude intensity is greater than the second amplitude intensity. For example, the first button 410 is used to increase the vibration intensity of the second working part 210 to... The second button 420 is used to reduce the vibration intensity of the second working part, or the first button 410 is used to reduce the vibration intensity of the second working part 210 and the second button 420 is used to increase the vibration intensity of the second working part; wherein, the pressing surface 401 of the first button 410 has identification texture 402, which is formed by protrusions and / or grooves, so that the user can distinguish the first button 410 and the second button 420 by touch without visual inspection, or the pressing surface 401 of the second button 420 has identification texture 402.

[0038] Optionally, the first button 410 and the second button 420 are spaced apart in the extension direction perpendicular to the excitation surface 240 of the second portion 200, in which the index finger has a greater range of motion, thereby facilitating the operator to adjust the vibration intensity; Optionally, the first button 410 and the second button 420 are spaced apart along the extension direction of the second portion 200, in which the two buttons have a larger installation space, allowing the area of ​​the pressing surface 401 of the two buttons to be set to a larger size, or the distance between the two buttons to be set to a larger size, thereby reducing the risk of the user accidentally pressing the other button.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
