Description

Surgical clamping appliance TECHNICAL FIELD

[0001] The present application relates to the technical field of surgical auxiliary instruments, in particular to a surgical clamping appliance. BACKGROUND

[0002] In the operation of the laryngeal tube, the laryngeal tube tissue is often resected or repaired. Since the recurrent laryngeal nerve is relatively close to the operation area, in this process, pulling or direct contact can cause nerve paralysis or injury, so the state of the recurrent laryngeal nerve needs to be monitored at all times.

[0003] At present, in the operation of the recurrent laryngeal nerve, in order to monitor the recurrent laryngeal nerve, a tracheal tube with a surface laryngeal recurrent nerve electrode is inserted into the laryngeal tube and the laryngeal recurrent nerve electrode is in contact with the vocal cord. The laryngeal recurrent nerve electrode is connected to an external nerve monitor, and the external nerve monitor is also electrically connected to a probe through a wire to realize the output of electric current. In actual use, the probe needs to touch the recurrent laryngeal nerve, and the external nerve monitor releases an electric signal to directly stimulate the recurrent laryngeal nerve. The recurrent laryngeal nerve transmits the electric stimulation to make the vocal cord muscle produce a muscle electric signal. The laryngeal recurrent nerve electrode on the surface of the tracheal tube in contact with the vocal cord receives the muscle electric signal and transmits it to the external nerve monitor. The doctor can accurately judge whether the recurrent laryngeal nerve is damaged by analyzing the waveform, amplitude and latency changes of the vocal cord muscle electric signal.

[0004] In the operation of the recurrent laryngeal nerve, the clamping appliance is one of the necessary surgical instruments. However, if the traditional nerve monitoring method is used, the surgical personnel need to replace the clamping appliance with a probe, then place the probe in the corresponding nerve tissue to monitor the recurrent laryngeal nerve, and then continue to use the clamping appliance for tissue stripping and other surgical operations. This will make the surgical process more complex. Moreover, the clamping part of the traditional clamping appliance is generally linear, so in some specific surgical scenarios, such as areas that need to be accessed through narrow areas or areas that can be reached only through curved parts with a certain radius, such as the deep throat or the inside of the wound, the clamping part of the linear clamping appliance cannot accurately clamp the blood vessels or tissues. The operator needs to adjust the angle of the handheld clamping appliance significantly to reach the corresponding area. This method will also increase the complexity of the operation to some extent, and there is room for improvement.

[0005] Content of the utility model

[0006] In order to overcome the problems in the operation of the recurrent laryngeal nerve, the present application provides a surgical clamping appliance.

[0007] The surgical clamping appliance provided by the present application adopts the following technical scheme.

[0008] The utility model provides a surgical clamping appliance, including clamping appliance body, the clamping appliance body includes clamping part, control part and hand -held part, the clamping part is bent, and the bending angle of clamping part is between 15 DEG and 95 DEG, the clamping appliance body is made of conductive metal, the clamping part, control part and hand -held part surface still all are provided with insulating coating, and the end of clamping part is provided with transmission part for transmitting electric signal, and the hand -held part is provided with electric signal receiving port for connecting nerve monitor, and the electric signal receiving port is electrically connected with transmission part through the conductive metal of clamping appliance body.

[0009] Through the above technical scheme, the bent clamping part design makes it applicable to narrow areas that need to be accessed or areas that need to pass through a curved part with a certain arc to reach, such as the deep throat or the inside of a wound. The operator can conveniently clamp directly without changing the hand-holding angle, without disturbing the surrounding tissue, thereby improving work efficiency. During surgery, the clamping appliance body can also transmit the electric stimulation emitted by the nerve signal monitor connected to the electric signal receiving port. The electric stimulation is transmitted to the recurrent laryngeal nerve through the transmission part of the clamping part and causes the vocal cord muscle to generate a muscle electrical signal. The muscle electrical signal is transmitted to the nerve monitor through the recurrent laryngeal nerve electrode on the tracheal tube, making it easier for the doctor to determine whether the recurrent laryngeal nerve is damaged. The clamping appliance in combination with the nerve monitor can efficiently and accurately monitor the state of the recurrent laryngeal nerve during the operation. The setting of the insulating coating prevents the electric stimulation from being mistakenly transmitted to other places and prevents the electric signal from being mistakenly transmitted from other parts of the forceps body, improving the accuracy of monitoring and reducing the risk of surgery.

[0010] Preferably, two clamping parts are provided, each having a clamping surface, and the two clamping surfaces are oppositely arranged.

[0011] The provision of the clamping surface increases the clamping area, making the clamping more stable.

[0012] Preferably, the clamping surface is provided with anti-slip lines.

[0013] By providing anti-slip lines on the clamping surface, the friction of the clamping part during clamping can be increased, making the clamping more stable.

[0014] Preferably, the anti-slip lines are arranged in multiple parallel lines.

[0015] By adopting the above technical scheme, the anti-slip lines are arranged in multiple parallel lines, which can further increase the friction of the clamping part during clamping, making the clamping part more stable during surgical clamping.

[0016] Preferably, the connecting end surface of the clamping part and the control part and the connecting surface of the adjacent anti-slip lines are both arc surfaces.

[0017] The connecting end surface of the clamping part and the control part and the connecting surface of the adjacent anti-skid lines are both arc surfaces, so that the nerves are not damaged during use, and the safety of the operation is improved.

[0018] Preferably, two hand-held parts are arranged, and control supports for controlling the clamping force of the clamping part are arranged on the two hand-held parts.

[0019] The control supports arranged on the hand-held parts can be in abutting connection during clamping, so that the clamping force is prevented from being too large, the damage to the nerve tissue is reduced, and the clamping device is more stable.

[0020] Preferably, the control supports arranged oppositely are both provided with corrugated structures for staggered abutting connection.

[0021] The corrugated structures on the control supports can make the clamping device suitable for clamping tissues of different sizes, can provide different control effects, and improve the safety of the operation.

[0022] Preferably, the electric signal receiving port is arranged at the connection between the hand-held part and the control support and faces away from the clamping part.

[0023] The electric signal receiving port faces away from the clamping part, so that the nerve monitor is facilitated to be connected, the interference with the clamping device is reduced, and the convenience of operation is improved.

[0024] In summary, the present application has at least one of the following beneficial technical effects:

[0025] 1. The bending angle of the clamping part is 15° to 95°, which can be suitable for operation in the deep throat or inside the wound, and the clamping part can also transmit electric signals, which can transmit electric signals through the clamping part to stimulate the operation area and monitor the recurrent laryngeal nerve.

[0026] 2. The design of the insulating coating and the anti-skid lines in the present application not only enhances the stability of clamping, but also avoids the transmission of electric stimulation to the arm, increases the friction force, and accurately monitors the nerve electric signal, further reduces the risk of nerve damage during the operation, and improves the efficiency of the operation.

[0030] The application will be further described in detail below in combination with Fig. 1.

[0031] Example 1

[0032] Referring to Fig. 1, the present embodiment discloses a clamping appliance for surgery, which comprises a clamping appliance body, the clamping appliance body comprising a clamping part 1, a control part 2 and a hand-holding part 3. In the present embodiment, the clamping appliance body is provided as a forceps body structure such as a hemostat, i.e., the clamping part 1 is a forceps beak, the control part 2 is a forceps body, and the hand-holding part 3 is a handle.

[0033] Referring to Fig. 1, the clamping part 1 is in a bent shape, and the bending angle can be between 15° and 95° to adapt to different surgical requirements. The clamping appliance body is provided as a conductive metal such as a metal material such as stainless steel, and an insulating coating is provided on the surfaces of the clamping part 1, the control part 2 and the hand-holding part 3. An end of the clamping part 1 is provided with a transmission part 11 for transmitting electric signals, and the transmission part 11 is not provided with an insulating coating, i.e., the conductive metal is exposed to the outside to realize the function of electric conduction at the end of the clamping part 1. The hand-holding part 3 is provided with an electric signal receiving port 4 for connecting a nerve monitor, and the electric signal receiving port 4 is electrically connected with the transmission part 11 through the conductive metal in the clamping appliance body.

[0034] In the present embodiment, the bending angle of the clamping part 1 is 90°, so that the operator can directly clamp without changing the hand-holding angle in the deep throat or inside the wound, without disturbing the surrounding tissues, and improving the work efficiency. The insulating coating provided on the surfaces of the clamping part 1, the control part 2 and the hand-holding part 3 avoids the electric stimulation from being wrongly transmitted to other places and avoids the electric signals from being wrongly transmitted by other places of the forceps body, to ensure that the electric signals can be smoothly transmitted to the recurrent laryngeal nerve. The hand-holding part 3 is provided with the electric signal receiving port 4, which is electrically connected with the transmission part 11 through the conductive metal in the clamping appliance body, to receive the electric signals emitted by the nerve monitor and transmit the electric signals emitted by the nerve monitor to the transmission part 11, so as to make the recurrent laryngeal nerve transmit electric stimulation, make the vocal cord muscle generate myoelectric signals, and then feed back the myoelectric signals to the nerve monitoring instrument through the recurrent laryngeal nerve electrode, to facilitate the doctor to judge whether the recurrent laryngeal nerve is damaged and accurately monitor the state of the recurrent laryngeal nerve.

[0035] Referring to Fig. 1, the clamping part 1 is designed in more detail. Specifically, the two clamping parts 1 are each provided with a clamping surface 12, the two clamping surfaces 12 are oppositely arranged, and the part where the two clamping surfaces 12 contact to clamp is provided with anti-skid lines 13. The clamping surface 12 and the anti-skid lines 13 increase the contact area with the human tissue. The anti-skid lines 13 can also increase the friction with the human tissue, enhance the stability of clamping, and prevent unnecessary damage to the patient caused by unstable clamping during the operation.

[0036] Referring to Fig. 1, the anti-skid lines 13 are designed as a plurality of lines, and the plurality of anti-skid lines 13 are parallel to each other. The design of the anti-skid lines 13 ensures the stability of clamping and does not cause excessive compression to the nerve tissue. In addition, the connecting end surface of the clamping part 1 and the control part 2 and the connection between the adjacent anti-skid lines 13 are integrally formed as a smooth arc surface. This design can effectively avoid the situation that the nerve tissue may be clamped off during the operation, thereby reducing the risk of damage to the nerve tissue.

[0037] Referring to Fig. 1, any hand-held part 3 is provided with a control bracket 31. Any control bracket 31 is located in the same plane as the corresponding hand-held part 3, and any control bracket 31 is designed as a cuboid and is fixedly connected with the corresponding hand-held part 3. The control bracket 31 is also provided with an insulating coating, and the control bracket 31 is provided with a corrugated structure 32 for mutual staggered abutting cooperation. During clamping, the two control brackets 31 abut against each other to control clamping. Since the sizes and thicknesses of different tissues are different, different clamping actions are required, so the positions where the corrugated structures 32 of the two control brackets 31 abut against each other are different when clamping different tissues, thereby different control clamping is performed, thus being suitable for clamping various tissues, enhancing the stability during clamping, reducing damage to the nerve tissue, and thus helping the doctor to maintain a more precise operation state.

[0038] Referring to Fig. 1, the electrical signal receiving port 4 is located at the connection between the hand-held part 3 and the control bracket 31 and faces away from the clamping part 1. The position of the electrical signal receiving port 4 is designed to facilitate the placement of the wire connected to the nerve monitor between the two hand-held parts 3, facilitate the connection of the nerve monitor, reduce the interference to the hemostat during work, and increase the convenience of operation.

[0039] The implementation principle of the embodiment of the present application is that when the hemostatic forceps is used for surgery, the clamping part 1 is designed in a 90° bent shape, so that when operating in a narrow space, the bent clamping part 1 can provide a more flexible operating angle and will not interfere with the surrounding tissues, thereby improving the work efficiency. During the surgery, the transmission part 11 of the clamping part 1 can also transmit the electric stimulus emitted by the nerve signal monitor connected to the electric signal receiving port 4, and the electric stimulus is transmitted to the recurrent laryngeal nerve through the clamping part 1 and makes the vocal cord muscle produce a muscle electric signal, and the muscle electric signal is transmitted to the nerve monitor through the recurrent laryngeal nerve electrode on the tracheal catheter, so as to facilitate the doctor to judge whether the recurrent laryngeal nerve is damaged, so that the doctor can quickly and accurately grasp the real-time state of the nerve.

[0040] Embodiment two

[0041] The specific difference between the embodiment of the present application and the application embodiment one is that:

[0042] Referring to FIG. 2, in the embodiment of the present application, the clamping device body is provided as a pair of tweezers or a pair of tweezers type structure, that is, the clamping part 1 is a clamping head, the control part 2 is a clamping arm, the hand holding part 3 is a handle, and no control bracket 31 is required between adjacent clamping arms.

[0043] The implementation principle of the embodiment of the present application is that when the tweezers is used for surgery, the clamping part 1 is designed in a 90° bent shape, so that when operating in a narrow space, the bent clamping part 1 can provide a more flexible operating angle and will not interfere with the surrounding tissues, thereby improving the work efficiency. During the surgery, the transmission part 11 of the clamping part 1 can also transmit the electric stimulus emitted by the nerve signal monitor connected to the electric signal receiving port 4, and the electric stimulus is transmitted to the recurrent laryngeal nerve through the clamping part 1 and makes the vocal cord muscle produce a muscle electric signal, and the muscle electric signal is transmitted to the nerve monitor through the recurrent laryngeal nerve electrode on the tracheal catheter, so as to facilitate the doctor to judge whether the recurrent laryngeal nerve is damaged, so that the doctor can quickly and accurately grasp the real-time state of the nerve.

[0044] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
