Description

[0001] This application claims priority to Chinese patent application No. 2025227315051, filed on December 23, 2025, entitled "Mirror-Clamping Composite Instrument", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of medical device technology, and in particular to a combination of endoscope and forceps. Background Technology

[0003] In traditional techniques, endoscopes and foreign body forceps are kept separate and independent. In clinical practice, however, endoscopes and foreign body forceps are often used together to remove foreign objects from the body. The procedure is roughly as follows: The doctor first inserts the endoscope into the patient's body, using the lens and light source to observe the location and shape of the foreign object. Then, the doctor inserts the foreign body forceps into the instrument channel on the endoscope, allowing the forceps to proceed along the channel into the patient's body. The endoscope provides both the "channel" and the "visualization," enabling the forceps to accurately reach the target location. Guided by the endoscopic view, the doctor manipulates the handle of the forceps to grasp the foreign object. After securing the object, the forceps are slowly withdrawn along with the endoscope, ensuring the foreign object does not dislodge or damage the mucous membrane.

[0004] However, since the endoscope and foreign body forceps are independent structures, when using them together, the doctor must always operate the endoscope with one hand and the foreign body forceps with the other. This increases the doctor's workload, causes inconvenience, and hinders the doctor from completing the surgery efficiently and conveniently. Summary of the Invention

[0005] Therefore, it is necessary to provide a combined mirror-clamp instrument to address the above problems.

[0006] To address the above problems, this application provides the following technical solution: A vibro-clamp compound instrument, the vibro-clamp compound instrument comprising: An endoscope having an insertion part and an operating part, the insertion part having an instrument channel and the operating part having an operating part housing; The foreign body forceps includes a forceps head, a forceps tube, a traction wire, and a control handle. The forceps tube passes through the instrument channel, and the traction wire passes through the forceps tube. The two ends of the traction wire are connected to the forceps head and the control handle, respectively. The control handle is partially confined within the operating unit housing to be integrated with the operating unit. The control handle includes a movable ring. Both the movable ring and the forceps head are located outside the endoscope. The movable ring can open and close relative to the operating unit housing, and during this opening and closing process, the movable ring can move the traction wire relative to the forceps tube. The lens clamp compound is configured to allow the operator to operate the movable ring to open and close relative to the operating part housing with one hand.

[0007] This endoscopic clamp device has at least the following beneficial effects: When using this endoscope-forceps combination instrument, the doctor can hold the instrument with one hand and manipulate the movable ring to open and close relative to the outer shell of the operating part. This moves the traction wire relative to the forceps tube, thereby controlling the opening and closing of the forceps head to retrieve the foreign body. Then, by retracting the arm holding the instrument, the forceps and endoscope can be moved back together to remove the foreign body.

[0008] In summary, doctors only need one hand to operate the endoscopic forceps instrument, eliminating the need for both hands. This reduces the doctor's workload, makes the procedure easier, and helps doctors complete the surgery efficiently and conveniently.

[0009] In one embodiment, the control handle further includes a connecting seat, a connecting rod, a connecting rod, a movable receiving member, a fixed receiving member, a first receiving member, and a second receiving member; the connecting seat is fixedly connected to the movable ring, the connecting rod is rotatably connected to the connecting seat, and the connecting rod is fixedly connected to the connecting seat; the connecting seat, the connecting rod, and the connecting rod are arranged in a "Y" shape; both the movable receiving member and the fixed receiving member are confined within the operating part housing; the movable receiving member is fixedly connected to the connecting rod, and the fixed receiving member is fixedly connected to the connecting rod; when the movable ring is closed relative to the operating part housing... During the process, the portion of the movable receiving member away from the movable ring can abut against the inner wall of the operating part housing; during the opening of the movable ring relative to the operating part housing, the portion of the movable receiving member near the movable ring can abut against the inner wall of the operating part housing; the traction wire passes through the movable receiving member and the fixed receiving member, the first receiving member is relatively far from the proximal end of the insertion part and located within the movable receiving member, and the second receiving member is relatively close to the proximal end of the insertion part and located within the fixed receiving member; the first receiving member is fixed to the traction wire, and the second receiving member is fixed to the clamp tube.

[0010] This configuration allows the single hand holding the vibratory forceps to grip tightly, causing the movable ring to close relative to the operating part housing. After the movable receiving part, away from the movable ring, abuts against the wall of the slide, the connecting rod rotates relative to the connecting seat. The movable receiving part moves away from the fixed receiving part, increasing the distance between the movable and fixed receiving parts. Consequently, the distance between the first and second receiving parts also increases, causing the traction wire to move away from the forceps head relative to the forceps tube, thereby controlling the closing of the forceps head.

[0011] The single hand holding the vibratory forceps compound instrument is opened, thereby opening the movable finger ring relative to the operating part housing. After the movable receiving part near the movable finger ring abuts against the wall of the slide, the connecting rod rotates in the opposite direction relative to the connecting seat. The movable receiving part moves towards the fixed receiving part, and the distance between the movable receiving part and the fixed receiving part decreases. The distance between the first receiving part and the second receiving part also decreases, and the traction wire moves relative to the forceps tube in the direction closer to the forceps head, thereby controlling the opening of the forceps head.

[0012] In one embodiment, a slide is provided on the inner wall of the operating part housing, and both the movable receiving member and the fixed receiving member are confined within the slide and are configured to slide relative to the slide.

[0013] With this configuration, moving the movable ring along the length of the slide causes the connecting seat, connecting rod, connecting rod, movable receiving part, fixed receiving part, first receiving part, second receiving part, traction wire, clamp tube, and clamp head to move together with the movable ring, thus adjusting the position of the clamp head relative to the insertion part.

[0014] In one embodiment, the length direction of the slide is consistent with the length direction of the instrument channel.

[0015] This design facilitates the movement of the traction wire and clamp tube.

[0016] In one embodiment, a fixing ring is provided on the outer wall of the operating part housing; The fixed ring and the movable ring are located on the other side of the operating part housing, and the fixed ring is closer to the proximal end of the insertion part than the movable ring; or, The fixed ring and the movable ring are arranged in a layout similar to the two handles of scissors.

[0017] This design allows doctors to adjust the position of the forceps head relative to the insertion point with one hand.

[0018] In one embodiment, the operating part housing includes a first half-shell and a second half-shell, the first half-shell and the second half-shell being detachably connected and jointly enclosing the slide rail; when the first half-shell and the second half-shell are separated, both the movable receiving member and the fixed receiving member can leave the slide rail, the first receiving member can leave the movable receiving member, and the second receiving member can leave the fixed receiving member.

[0019] With this setup, after disassembling the first and second halves of the shell, the movable ring, connecting seat, connecting rod, connecting rod, movable receiving part, and fixed receiving part can be removed. Then, the first receiving part can be removed from the movable receiving part, and the second receiving part can be removed from the fixed receiving part. After that, the traction wire and forceps head can be pulled out from the instrument channel. This allows for the separation of the foreign body forceps from the endoscope, facilitating the separate cleaning, disinfection, and sterilization of the foreign body forceps and the endoscope.

[0020] In one embodiment, both the movable receiving member and the fixed receiving member are annular structures, and the axis of the movable receiving member, the axis of the fixed receiving member, and the axis of rotation of the connecting rod relative to the connecting seat are parallel to each other.

[0021] With this configuration, both the circumferential surfaces of the movable and fixed accommodating parts make line contact with the slide rail, resulting in low friction. This facilitates the movement of the movable and fixed accommodating parts within the slide rail.

[0022] In one embodiment, the movable receiving member is provided with a first arc-shaped hole, which is coaxial with the movable receiving member and extends through the movable receiving member along the extension direction of the traction wire; the fixed receiving member is provided with a second arc-shaped hole, which is coaxial with the fixed receiving member and extends through the fixed receiving member along the extension direction of the traction wire; the first arc-shaped hole, the second arc-shaped hole, and the traction wire are aligned; there are two of each of the first arc-shaped hole and the second arc-shaped hole, with the two first arc-shaped holes facing each other along the extension direction of the traction wire, and the two second arc-shaped holes facing each other along the extension direction of the traction wire.

[0023] With this configuration, during the opening and closing of the movable ring relative to the outer shell of the operating part, the first and second arc holes provide space for the traction wire to move, which can improve the stress state of the traction wire and facilitate the control of the traction wire.

[0024] In one embodiment, both the first accommodating member and the second accommodating member are spherical structures.

[0025] This design facilitates the movement of the first accommodating element within the movable accommodating element and the movement of the second accommodating element within the fixed accommodating element, thereby improving the stress state of the traction wire and making it easier to control the traction wire.

[0026] In one embodiment, the connecting seat is located on the outer side of the portion of the movable ring that is relatively close to the proximal end of the insertion portion.

[0027] This design facilitates the opening and closing of the movable ring relative to the operating part housing, and also facilitates the movement of the traction wire relative to the clamp tube during the opening and closing process of the movable ring relative to the operating part housing.

[0028] In one embodiment, a fixed finger ring is provided on the outer wall of the operating part housing; the fixed finger ring and the movable finger ring are arranged in a layout similar to the two handles of scissors; the fixed finger ring and the movable finger ring are respectively located on the top side and the bottom side of the operating part housing.

[0029] With this setup, the operator can pass their thumb through the fixed ring and the other four fingers through the movable ring. The doctor can then adjust the position of the forceps head relative to the insertion point by moving the thumb forward or backward relative to the other four fingers, thus moving the movable ring forward or backward relative to the fixed ring. Alternatively, the operator can pass only three, two, or one of the other four fingers through the movable ring. The doctor can then adjust the position of the forceps head relative to the insertion point by moving the thumb forward or backward relative to the other four fingers, thus moving the movable ring forward or backward relative to the fixed ring.

[0038] See Figures 1 to 14 This application provides a endoscopic forceps composite device, which includes an endoscope 1 and foreign body forceps 2.

[0039] See Figure 1 , Figure 2 , Figures 6 to 8 The endoscope 1 has an insertion part 12 and an operation part 11. The insertion part 12 has an instrument channel 121, and the operation part 11 has an operation part housing 111.

[0040] See Figures 1 to 4The foreign body forceps 2 includes a forceps head 21, a forceps tube 22, a traction wire 23, and a control handle 24. The forceps tube 22 passes through the instrument channel 121, and the traction wire 23 passes through the forceps tube 22. The two ends of the traction wire 23 are connected to the forceps head 21 and the control handle 24, respectively. The control handle 24 is partially confined within the operating unit housing 111 to be integrated with the operating unit 11. The control handle 24 includes a movable finger ring 241. Both the movable finger ring 241 and the forceps head 21 are located outside the endoscope 1. The movable finger ring 241 can open and close relative to the operating unit housing 111. During the opening and closing process relative to the operating unit housing 111, the movable finger ring 241 can drive the traction wire 23 to move relative to the forceps tube 22.

[0041] See Figures 12 to 14 The vibratory clamp compound is configured to allow the operator to operate the movable ring 241 with one hand to open and close relative to the operating unit housing 111.

[0042] During the use of this endoscope-forceps combined instrument, the doctor can hold the instrument with one hand and manipulate the movable ring 241 to open and close relative to the operating part housing 111, thereby moving the traction wire 23 relative to the forceps tube 22, and thus controlling the opening and closing of the forceps head 21 to complete the foreign body retrieval. Afterwards, by using the arm to pull back the one hand holding the endoscope-forceps combined instrument, the foreign body forceps 2 and the endoscope 1 can be pulled back together to remove the foreign body.

[0043] In summary, doctors only need one hand to operate the endoscopic forceps instrument, eliminating the need for both hands. This reduces the doctor's workload, makes the procedure easier, and helps doctors complete the surgery efficiently and conveniently.

[0044] For example, the traction wire 23 is a steel wire.

[0045] In this application, the relevant technical features of controlling the opening and closing of the clamp head 21 by moving the traction wire 23 relative to the clamp tube 22 can be adopted from the prior art, and will not be described in detail here.

[0046] See Figure 2 , Figure 3 , Figures 9 to 11The control handle 24 also includes a connecting seat 242, a connecting rod 243, a connecting rod 244, a movable receiving member 245, a fixed receiving member 246, a first receiving member 247, and a second receiving member 248. The connecting seat 242 is fixedly connected to the movable ring 241, the connecting rod 243 is rotatably connected to the connecting seat 242, and the connecting rod 244 is fixedly connected to the connecting seat 242. The connecting seat 242, connecting rod 243, and connecting rod 244 are arranged in a "Y" shape. Both the movable receiving member 245 and the fixed receiving member 246 are confined within the operating part housing 111. The movable receiving member 245 is fixedly connected to the connecting rod 243, and the fixed receiving member 246 is fixedly connected to the connecting rod 244. During the closing process of the movable ring 241 relative to the operating part housing 111, the portion of the movable receiving member 245 away from the movable ring 241 can abut against the inner wall of the operating part housing 111. As the movable ring 241 opens relative to the operating part housing 111, the portion of the movable receiving member 245 near the movable ring 241 abuts against the inner wall of the operating part housing 111. The traction wire 23 passes through the movable receiving member 245 and the fixed receiving member 246. The first receiving member 247 is relatively far from the proximal end of the insertion part 12 and located within the movable receiving member 245, while the second receiving member 248 is relatively close to the proximal end of the insertion part 12 and located within the fixed receiving member 246. The first receiving member 247 is fixed to the traction wire 23, and the second receiving member 248 is fixed to the clamp tube 22.

[0047] Squeeze the vibratory forceps instrument with one hand (e.g.) Figure 13 As shown), the movable ring 241 closes relative to the operating part housing 111. After the portion of the movable receiving member 245 away from the movable ring 241 abuts against the wall of the slide rail 1113, the connecting rod 243 rotates relative to the connecting seat 242. The movable receiving member 245 moves away from the fixed receiving member 246, and the distance between the movable receiving member 245 and the fixed receiving member 246 increases. The distance between the first receiving member 247 and the second receiving member 248 also increases. The traction wire 23 moves away from the clamp head 21 relative to the clamp tube 22, thereby controlling the clamp head 21 to close.

[0048] Open the single hand holding the vibratory forceps instrument (e.g.) Figure 12 As shown), the movable ring 241 opens relative to the operating part housing 111. After the portion of the movable receiving member 245 near the movable ring 241 abuts against the wall of the slide rail 1113, the connecting rod 243 rotates in the opposite direction relative to the connecting seat 242. The movable receiving member 245 moves towards the fixed receiving member 246, and the distance between the movable receiving member 245 and the fixed receiving member 246 decreases. The distance between the first receiving member 247 and the second receiving member 248 also decreases, and the traction wire 23 moves relative to the clamp tube 22 in the direction close to the clamp head 21, thereby controlling the clamp head 21 to open.

[0049] See Figure 2 and Figure 5 The inner wall of the operating unit housing 111 is provided with a slide rail 1113. Both the movable receiving member 245 and the fixed receiving member 246 are confined within the slide rail 1113 and are configured to slide relative to it. Moving the movable ring 241 along the length of the slide rail 1113 causes the connecting seat 242, connecting rod 243, connecting rod 244, movable receiving member 245, fixed receiving member 246, first receiving member 247, second receiving member 248, traction wire 23, forceps tube 22, and forceps head 21 to move together with the movable ring 241, thus adjusting the position of the forceps head 21 relative to the insertion part 12. In other words, the doctor can operate the opening and closing of the forceps head 21 with one hand to grasp foreign objects, and can also adjust the position of the forceps head 21 relative to the insertion part 12 with one hand, without needing to use both hands. This reduces the doctor's workload, facilitates operation, and helps the doctor complete the surgery efficiently and conveniently.

[0050] See Figure 2 The length direction of the slide 1113 is consistent with the length direction of the instrument channel 121. This facilitates the movement of the traction wire 23 and the clamp tube 22.

[0051] See Figure 1 , Figure 2 , Figures 5 to 7 A fixing ring 113 is provided on the outer wall of the operating part housing 111.

[0052] See Figure 1 , Figure 2 , Figures 5 to 7 In some embodiments, the fixed finger ring 113 and the movable finger ring 241 are located on the same side of the operating part housing 111, with the fixed finger ring 113 closer to the proximal end of the insertion part 12 than the movable finger ring 241. This allows the physician to hold the endoscopic forceps compound instrument with one hand, pressing their thumb against the operating part housing 111 or a structure on the operating part housing 111, passing their index finger through the fixed finger ring 113, and passing the other three fingers through the movable finger ring 241. Here, "the other three fingers" refers to the middle, ring, and little fingers. For ease of description below, "the other three fingers" will be used consistently to refer to this combination of the middle, ring, and little fingers. By moving the index finger away from or closer to the other three fingers, the movable finger ring 241 moves relative to the fixed finger ring 113. The connecting seat 242, connecting rod 243, connecting rod 244, movable receiving member 245, fixed receiving member 246, first receiving member 247, second receiving member 248, traction wire 23, clamp tube 22 and clamp head 21 move together with the movable finger ring 241, thereby adjusting the position of the clamp head 21 relative to the insertion part 12.

[0053] See Figure 15 and Figure 16In other embodiments, the fixed ring 113 and the movable ring 241 are arranged in a manner similar to the two handles of scissors. Specifically, the fixed ring 113 and the movable ring 241 are located on the top and bottom sides of the operating part housing 111, respectively. The operator can pass the thumb of one hand through the fixed ring 113 and the other four fingers of the same hand through the movable ring 241. The doctor can adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to the other four fingers, thereby moving the movable ring 241 forward or backward relative to the fixed ring 113. Of course, the operator can also pass some of the other four fingers of one hand (i.e., three fingers, two fingers, or one finger) through the movable ring 241. The doctor can adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to some of the other four fingers, thereby moving the movable ring 241 forward or backward relative to the fixed ring 113.

[0054] In some embodiments, the fixed ring 113 and the movable ring 241 are arranged in a manner similar to the two handles of scissors, and the fixed ring 113 and the movable ring 241 are located on the bottom and top sides of the operating part housing 111, respectively. The operator can pass the thumb of one hand through the movable ring 241 and the other four fingers of the same hand through the fixed ring 113. The doctor can adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to the other four fingers, thereby moving the fixed ring 113 forward or backward relative to the movable ring 241. Alternatively, the operator can pass some of the other four fingers of one hand (i.e., three, two, or one finger) through the fixed ring 113, and adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to some of the other four fingers, thereby moving the fixed ring 113 forward or backward relative to the movable ring 241.

[0055] In some embodiments, the endoscope forceps compound instrument does not include a fixed finger ring 113, and a movable finger ring 241 is located on the bottom side of the operating part housing 111. The operator bends the thumb of one hand and holds it firmly against the top of the operating part housing 111, passing the other four fingers of the one hand through the movable finger ring 241. The operator can adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to the other four fingers, thereby moving the movable finger ring 241 forward or backward relative to the operating part housing 111. Alternatively, the operator can pass some of the other four fingers of the one hand (i.e., three fingers, two fingers, or one finger) through the movable finger ring 241, and adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to some of the other four fingers. The doctor can grip the operating part housing 111 with their thumb and squeeze it with one hand, thereby closing the movable ring 241 relative to the operating part housing 111; or, with the thumb gripping the operating part housing 111, open the hand, thereby opening the movable ring 241 relative to the operating part housing 111. It is understood that in these embodiments, the movement is primarily achieved by the active movement of the fingers other than the thumb, causing the thumb to move forward or backward relative to the other fingers.

[0056] In some embodiments, the endoscope-forceps compound instrument does not include a fixed finger ring 113, and a movable finger ring 241 is located on the top side of the operating part housing 111. The operator inserts the thumb of one hand through the movable finger ring 241 and bends the other four fingers of the same hand to hold the bottom of the operating part housing 111. The operator can adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to the other four fingers, thereby moving the movable finger ring 241 forward or backward relative to the operating part housing 111. Alternatively, the operator can bend some of the other four fingers of one hand (i.e., three, two, or one finger) to hold the bottom of the operating part housing 111, and adjust the position of the forceps head 21 relative to the insertion part 12 by moving the thumb forward or backward relative to some of the other four fingers. The doctor can grip the operating part housing 111 with the other four fingers or some of the other four fingers of one hand, thus closing the movable ring 241 relative to the operating part housing 111; conversely, the doctor can open the hand with the other four fingers or some of the other four fingers gripping the operating part housing 111, thus opening the movable ring 241 relative to the operating part housing 111. It is understood that in these embodiments, the movement is primarily driven by the active movement of the thumb, causing the thumb to move forward or backward relative to the other fingers.

[0057] See Figure 1 and Figure 2The operating unit housing 111 includes a first half-shell 1111 and a second half-shell 1112. The first half-shell 1111 and the second half-shell 1112 are detachably connected and together enclose a slide rail 1113. When the first half-shell 1111 and the second half-shell 1112 are separated, both the movable receiving member 245 and the fixed receiving member 246 can leave the slide rail 1113, the first received member 247 can leave the movable receiving member 245, and the second received member 248 can leave the fixed receiving member 246. After disassembling the first half-shell 1111 and the second half-shell 1112, the movable ring 241, connecting seat 242, connecting rod 243, connecting rod 244, movable receiving part 245 and fixed receiving part 246 can be removed. Then, the first receiving part 247 can be removed from the movable receiving part 245 and the second receiving part 248 can be removed from the fixed receiving part 246. Then, the traction wire 23 and the forceps head 21 can be pulled out from the instrument channel 121. This can separate the foreign body forceps 2 from the endoscope 1, making it convenient to clean, disinfect and sterilize the foreign body forceps 2 and the endoscope 1 separately.

[0058] For example, the first half-shell 1111 and the second half-shell 1112 are threaded together or snapped together.

[0059] See Figure 9 and Figure 10 Both the movable receiving member 245 and the fixed receiving member 246 are annular structures. The axes of the movable receiving member 245, the fixed receiving member 246, and the rotation axis of the connecting rod 243 relative to the connecting seat 242 are parallel to each other. The circumferential surfaces of the movable receiving member 245 and the fixed receiving member 246 are in line contact with the slide rail 1113, resulting in low friction. This facilitates the movement of the movable receiving member 245 and the fixed receiving member 246 within the slide rail 1113.

[0060] See Figure 9 and Figure 10 The movable receiving member 245 has a first arc-shaped hole 2451, which is coaxial with the movable receiving member 245 and passes through the movable receiving member 245 along the extension direction of the traction wire 23. The fixed receiving member 246 has a second arc-shaped hole 2461, which is coaxial with the fixed receiving member 246 and passes through the fixed receiving member 246 along the extension direction of the traction wire 23. The first arc-shaped hole 2451, the second arc-shaped hole 2461, and the traction wire 23 are aligned. There are two of each type of arc-shaped hole 2451 and arc-shaped hole 2461. The two first arc-shaped holes 2451 are opposite each other along the extension direction of the traction wire 23, and the two second arc-shaped holes 2461 are opposite each other along the extension direction of the traction wire 23. During the opening and closing of the movable ring 241 relative to the operating part housing 111, the first arc hole 2451 and the second arc hole 2461 provide movement space for the traction wire 23, which can improve the stress state of the traction wire 23 and facilitate the operation of the traction wire 23.

[0061] See Figure 3 and Figure 11 Both the first receiving member 247 and the second receiving member 248 are spherical structures. This facilitates the movement of the first receiving member 247 within the movable receiving member 245 and the movement of the second receiving member 248 within the fixed receiving member 246, which helps to improve the stress state of the traction wire 23 and facilitates the control of the traction wire 23.

[0062] See Figure 3 and Figure 4 The connecting seat 242 is located on the outer side of the portion of the movable ring 241 that is relatively close to the proximal end of the insertion part 12. This facilitates the opening and closing of the movable ring 241 relative to the operating part housing 111, and facilitates the movement of the traction wire 23 relative to the clamp tube 22 during the opening and closing of the movable ring 241 relative to the operating part housing 111.

[0063] Preferably, the movable ring 241, connecting seat 242, connecting rod 244, and fixed receiving member 246 are integrally formed. On the one hand, this can reduce manufacturing costs; on the other hand, it helps to ensure the structural strength of the control handle 24.

[0064] See Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figures 12 to 14 The operating unit 11 also has an angle control knob 112 for controlling the bending of the insertion part 12, and the angle control knob 112 is rotatably connected to the operating unit housing 111. The angle control knob 112, the fixed finger ring 113, and the movable finger ring 241 are configured such that when the operator holds the vitreoretinal forceps compound instrument with one hand, the thumb can reach and operate the angle control knob 112 to rotate, the index finger can pass through the fixed finger ring 113, and the other three fingers can pass through the movable finger ring 241 and operate the movable finger ring 241 to slide relative to the slide rail 1113 and open and close relative to the operating unit housing 111.

[0065] In use Figures 12 to 14 During the procedure using the endoscopic forceps combined instrument, the surgeon can perform the surgical operation by holding the instrument with one hand as follows: pass the index finger through the fixed finger ring 113, pass the other three fingers through the movable finger ring 241, and press the thumb on the angle control knob 112 or the operating unit housing 111.

[0066] Specifically, surgical procedures can be performed while holding the endoscopic forceps instrument with one hand, as follows: 1. Keep the other three fingers and index finger relatively still, and use your arm to move the endoscope and forceps in one hand forward and backward, so that the endoscope 1 and the foreign body forceps 2 move forward and backward synchronously.

[0067] 2. Move your index finger away from the other three fingers, thereby moving the fixed finger ring 113 away from the movable finger ring 241. This causes the movable finger ring 241, the traction wire 23, and the pliers head 21 to retract relative to the fixed finger ring 113, and the pliers head 21 to gradually move closer to the insertion part 12. Move your index finger closer to the other three fingers, thereby moving the fixed finger ring 113 closer to the movable finger ring 241. This causes the movable finger ring 241, the traction wire 23, and the pliers head 21 to advance relative to the fixed finger ring 113, and the pliers head 21 to gradually move away from the insertion part 12. By moving the pliers head 21 closer to or further away from the insertion part 12, the position of the pliers head 21 relative to the insertion part 12 can be changed.

[0068] 3. Grip the vibratory forceps instrument firmly with one hand (e.g., ...). Figure 13 As shown), the movable ring 241 closes relative to the operating part housing 111; allowing the single hand holding the vibratory forceps compound instrument to open (as shown). Figure 12 As shown), the movable ring 241 opens relative to the operating part housing 111. By opening and closing the movable ring 241 relative to the operating part housing 111, the traction wire 23 can be moved relative to the clamp tube 22, thereby controlling the opening and closing of the clamp head 21.

[0069] 4. Press your thumb on the angle control knob 112 and push the angle control knob 112 forward or backward (e.g., Figure 13 and Figure 14 As shown), thereby adjusting the bending direction of the insertion part 12.

[0070] When it is not necessary to adjust the bending direction of the insertion part 12, the doctor presses his thumb on the operating part housing 111 (e.g., Figure 12 As shown), this avoids accidental changes in the bending direction of the insertion part 12 due to accidental force applied by the thumb to the angle control knob 112.

[0071] See Figure 1 and Figure 2 The angle control knob 112 has a force-receiving part 1121 for the operator to apply force. The force-receiving part 1121 is located on one side of the operating part housing 111 and is close to the fixed finger ring 113 and the movable finger ring 241. The fixed finger ring 113 and the movable finger ring 241 are located on the other side of the operating part housing 111, and the fixed finger ring 113 is closer to the proximal end of the insertion part 12 than the movable finger ring 241. This allows the doctor to easily hold the endoscopic forceps compound instrument with one hand to perform surgical operations.

[0072] See Figure 1 and Figure 2The outer shell 111 of the operating part protrudes towards the force-receiving part 1121 to form a semi-circular thumb rest 1114, and the rotation axis of the angle control knob 112 passes through the center of the thumb rest 1114. In this way, the rotation trajectory of the force-receiving part 1121 follows the outer contour of the thumb rest 1114. When the thumb applies force to the force-receiving part 1121 to push the angle control knob 112 to rotate, it can rest on the thumb rest 1114, which makes it convenient for the thumb to apply force to the angle control knob 112 and avoids the situation where the thumb is suspended in the air and it is inconvenient to apply force to the angle control knob 112.

[0073] See Figures 1 to 3 The movable ring 241 has a scissor handle structure. This makes it easier for the doctor to hold the movable ring 241, thereby making it easier for the doctor to hold the endoscopic forceps compound instrument.

[0074] See Figure 6 The operating unit housing 111 is provided with a clearance hole 1115, which communicates with the internal space of the slide rail 1113, and the control handle 24 passes through the clearance hole 1115.

[0075] In this application, the technical features related to the angle control knob 112 controlling the bending of the insertion part 12 can be adopted from the prior art, and will not be described in detail here.

[0076] See Figure 15 In some embodiments, a fixed finger ring 113 is provided on the outer wall of the operating part housing 111. The fixed finger ring 113 and the movable finger ring 241 are arranged in a layout similar to the two handles of scissors. The fixed finger ring 113 and the movable finger ring 241 are located on the top and bottom sides of the operating part housing 111, respectively. The operating part 11 also has an angle control knob 112 for controlling the bending of the insertion part 12, and the angle control knob 112 is rotatably connected to the operating part housing 111. The angle control knob 112 is located near the bottom side of the operating unit housing 111 and is closer to the proximal end of the insertion part 12 than the movable finger ring 241. The angle control knob 112, the fixed finger ring 113, and the movable finger ring 241 are configured such that when the operator holds the vibratory forceps compound instrument with one hand, the index finger can reach and operate the angle control knob 112 to rotate, the thumb can pass through the fixed finger ring 113, and the other three fingers can pass through the movable finger ring 241 to operate the movable finger ring 241 to slide relative to the slide rail 1113 and to open and close relative to the operating unit housing 111.

[0077] In use Figure 15 During the procedure using the endoscopic forceps combined instrument, the surgeon can perform surgical operations by holding the instrument with one hand as follows: The thumb is passed through the fixed finger ring 113, and the other three fingers are passed through the movable finger ring 241. Specifically, while holding the endoscopic forceps combined instrument with one hand, surgical operations can be performed as follows: 1. Keep the other three fingers and thumb relatively still, and use your arm to move the endoscope and forceps in one hand forward and backward, so that the endoscope 1 and the foreign body forceps 2 move forward and backward synchronously.

[0078] 2. Move the thumb forward relative to the other three fingers, thereby causing the movable ring 241 to retract relative to the fixed ring 113. This causes the movable ring 241, the traction wire 23, and the pliers head 21 to retract relative to the fixed ring 113, and the pliers head 21 to gradually move closer to the insertion part 12. Conversely, move the thumb backward relative to the other three fingers, thereby causing the movable ring 241 to advance relative to the fixed ring 113. This causes the movable ring 241, the traction wire 23, and the pliers head 21 to advance relative to the fixed ring 113, and the pliers head 21 to gradually move away from the insertion part 12. By moving the pliers head 21 closer to or further away from the insertion part 12, the position of the pliers head 21 relative to the insertion part 12 can be changed.

[0079] 3. When the hand holding the vibratory forceps instrument is squeezed tightly, the movable ring 241 closes relative to the operating part housing 111; when the hand holding the vibratory forceps instrument is opened, the movable ring 241 opens relative to the operating part housing 111. By opening and closing the movable ring 241 relative to the operating part housing 111, the traction wire 23 can be moved relative to the forceps tube 22, thereby controlling the opening and closing of the forceps head 21.

[0080] 4. Use your index finger to turn the angle control knob 112 to rotate it forward or backward, thereby adjusting the bending direction of the insertion part 12.

[0081] exist Figure 15 In the illustrated embodiment, preferably, the movable finger ring 241 is configured such that when the operator holds the endoscopic forceps compound instrument with one hand, the four fingers of the operator's hand other than the thumb can pass through the movable finger ring 241. When it is not necessary to adjust the bending direction of the insertion part 12, the doctor can also pass the index finger through the movable finger ring 241. On the one hand, this can prevent the index finger from accidentally applying force to the angle control knob 112, which could lead to an unintentional change in the bending direction of the insertion part 12. On the other hand, this allows the doctor to focus on changing the position of the forceps head 21 relative to the insertion part 12 and controlling the opening and closing of the forceps head 21, making it convenient for the doctor to apply force with one hand.

[0082] See Figure 16In some embodiments, a fixed finger ring 113 is provided on the outer wall of the operating part housing 111. The fixed finger ring 113 and the movable finger ring 241 are arranged in a layout similar to the two handles of scissors. The fixed finger ring 113 and the movable finger ring 241 are located on the top and bottom sides of the operating part housing 111, respectively. The operating part 11 also has an angle control knob 112 for controlling the bending of the insertion part 12, and the angle control knob 112 is rotatably connected to the operating part housing 111. The angle control knob 112 is located near the top side of the operating unit housing 111 and is closer to the proximal end of the insertion part 12 than the fixed finger ring 113. The angle control knob 112, the fixed finger ring 113, and the movable finger ring 241 are configured such that when the operator holds the vibratory forceps compound instrument with one hand, the thumb can enter and exit the fixed finger ring 113, and after the thumb is removed from the fixed finger ring 113, it can reach and operate the angle control knob 112 to rotate. The other four fingers can pass through the movable finger ring 241 and operate the movable finger ring 241 to slide relative to the slide rail 1113 and to open and close relative to the operating unit housing 111.

[0083] In use Figure 16 During the procedure using the endoscopic forceps combined instrument, the surgeon can perform the surgical operation by holding the instrument with one hand as follows: pass the thumb through the fixed finger ring 113 and pass the other four fingers through the movable finger ring 241.

[0084] Specifically, surgical procedures can be performed while holding the endoscopic forceps instrument with one hand, as follows: 1. Keep the other four fingers and thumb relatively still, and use your arm to move the endoscope and forceps in one hand forward and backward, so that the endoscope 1 and the foreign body forceps 2 move forward and backward synchronously.

[0085] 2. By moving the thumb forward relative to the other four fingers, the movable ring 241 moves backward relative to the fixed ring 113. This causes the movable ring 241, the traction wire 23, and the pliers head 21 to move backward relative to the fixed ring 113, and the pliers head 21 gradually moves closer to the insertion part 12. Conversely, by moving the thumb backward relative to the other four fingers, the movable ring 241 moves forward relative to the fixed ring 113. This causes the movable ring 241, the traction wire 23, and the pliers head 21 to move forward relative to the fixed ring 113, and the pliers head 21 gradually moves away from the insertion part 12. By moving the pliers head 21 closer to or further away from the insertion part 12, the position of the pliers head 21 relative to the insertion part 12 can be changed.

[0086] 3. When the hand holding the vibratory forceps instrument is squeezed tightly, the movable ring 241 closes relative to the operating part housing 111; when the hand holding the vibratory forceps instrument is opened, the movable ring 241 opens relative to the operating part housing 111. By opening and closing the movable ring 241 relative to the operating part housing 111, the traction wire 23 can be moved relative to the forceps tube 22, thereby controlling the opening and closing of the forceps head 21.

[0087] 4. Remove your thumb from the fixing ring 113 and press it on the angle control knob 112. Push the angle control knob 112 forward or backward to adjust the bending direction of the insertion part 12.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
