Description

[0002] Sinusitis and nasal polyps are common clinical diseases, with an incidence rate of 10%-20% in the population, of which 4%-10% of patients need to be treated by endoscopic nasal surgery. Endoscopic nasal surgery is mainly used for the surgical treatment of nasal diseases, and has gradually expanded to the transnasal surgical treatment of skull base diseases. In the process of endoscopic nasal surgery for maxillary sinus diseases such as maxillary sinus cysts and maxillary sinus polyps, it is usually necessary to clamp cysts, polyps and other target objects with the help of surgical clamps. During the operation, the surgeon needs to manipulate the surgical clamps to repeatedly test the angle and position, which is easy to damage the wound surface and increase the patient's pain. When removing cysts, polyps and other target objects in the sinus, because cysts and polyps are soft, smooth and easy to move, it is difficult for the surgical clamps to pull them into the jaws. Cysts and polyps are often not clamped smoothly by the jaws, and they need to be clamped repeatedly, which increases the difficulty of the operation and prolongs the operation time.

[0056] See also Figure 1 and Figure 2 As shown, a surgical instrument system is provided in one embodiment of the present application, and the surgical instrument system includes a surgical clamp 1000 and a control device 2000. The surgical clamp 1000 includes a clamp tube body 1100 and a clamping forceps head 1200. The inner cavity of the clamp tube body 1100 includes a plurality of axially penetrating unit channels. The clamp tube body 1100 includes a main tube segment 1110 and a curved tube segment 1120. The proximal end of the curved tube segment 1120 is connected to the distal end of the main tube segment 1110. The clamping forceps head 1200 is arranged at the distal end of the curved tube segment 1120. The control device 2000 is connected to the surgical clamp 1000, and is used to control at least one of the bending action of the curved tube segment 1120 and the opening and closing action of the clamping forceps head 1200.

[0057] The surgical clamp 1000 can perform opening and closing actions, and is used to clamp target objects such as polyps and cysts during surgery. With the cooperation of the endoscope, the operator can control the surgical clamp 1000 of the surgical instrument system to extend from the patient's nasal cavity and other locations. Since the shape of the nasal cavity and other locations has an arc, in this process, according to the patient's lesion location that needs to be reached, the operator can adjust the bending angle of the curved tube segment 1120 through the control device 2000 to adapt to the patient's nasal passage, so that the curved tube segment 1120 can smoothly pass through the nasal cavity and deliver the surgical clamp 1000 to the lesion location. With the help of the bending function of the curved tube segment 1120, the operator does not need to repeatedly test the angle and position, which greatly reduces the patient's pain and improves the efficiency of the operation. After the surgical clamp 1000 is delivered to the lesion location, the operator can control the surgical clamp 1000 through the control device 2000 to perform opening and closing actions to clamp target objects such as polyps and cysts. When removing target objects such as cysts and polyps, the bending function of the curved tube segment 1120 can align the surgical clamp 1000 with the cyst, polyp, etc. at an accurate angle and direction, so it can be pulled into the jaws more conveniently and the cyst or polyp can be clamped smoothly. There is no need to clamp repeatedly, which reduces the difficulty of the operation and shortens the operation time.

[0058] As one embodiment, the multiple unit channels of the clamp tube body 1100 may be only arranged in the main tube segment 1110, and the curved tube segment 1120 may be a lumen; the multiple unit channels of the clamp tube body 1100 may also be arranged through the main tube segment 1110 and the curved tube segment 1120; the arrangement of the multiple unit channels is not limited to this, and it is only necessary to facilitate the arrangement of the various functional elements extending from the proximal end to the distal end in the surgical instrument system, and the various functional elements may be the bending control wire body 2200b, the opening and closing control rod body 2300b, the suction tube body 3200b, the flushing tube body, the transmission wire, etc. as described below.

[0059] The control device 2000 includes a bending control assembly, which includes a bending main control component 2200a and a bending control line body 2200b. Figure 4 As shown, the unit channel of the clamp tube body 1100 includes an axially penetrating curved channel 1110a. For example, the inner cavity of the main tube section 1110 includes an axially penetrating curved channel 1110a, so that the bending control wire body 2200b is movably arranged in the curved channel 1110a, and the bending main control component 2200a is controllably connected with the bending tube section 1120 through the bending control wire body 2200b to control the bending action of the bending tube section 1120. The main tube section 1110 of the clamp tube body 1100 can be made of medical grade stainless steel with a certain strength, such as 304 stainless steel, 316 stainless steel, 420 stainless steel, 430 stainless steel, etc. The bending tube section 1120 of the clamp tube body 1100 can be made of an elastic bending structure such as a spring coil, which is easy to bend and has a certain resilience. The material of the bending control line 2200b can be selected from low-carbon steel, stainless steel, steel wire coated with corrosion-resistant materials, titanium or titanium alloy, or nickel-titanium wire, tungsten wire and other high-strength polymer materials such as nylon wire. Technical personnel in this field can choose according to their needs and there is no limitation here.

[0060] In one embodiment, the bending control assembly includes a shaft and a torsion spring, the torsion spring is mounted on the shaft, the shaft is elastically mounted on the clamping forceps head 1200 through the torsion spring, the distal end of the bending control wire 2200b is connected to the shaft through the inner cavity of the bending tube segment 1120, and is used to pull the bending tube segment 1120 to perform the bending action. When the operator tightens the bending control wire 2200b through the bending main control component 2200a, the bending tube segment 1120 will be controlled to bend, and the torsion spring will provide a torsion force. When the operator cancels the tightening of the bending control wire 2200b, the torsion force will cause the bending control wire 2200b to recover, thereby causing the bending of the bending tube segment 1120 to recover.

[0061] The control device 2000 includes an opening and closing control assembly, which includes an opening and closing main control component 2300a and an opening and closing control rod body 2300b. Figure 4As shown, the unit channel of the clamp pipe body 1100 includes an axially penetrating opening and closing channel 1110b. For example, the inner cavity of the main pipe section 1110 includes an axially penetrating opening and closing channel 1110b, so that the opening and closing control rod body 2300b is movably arranged in the opening and closing channel 1110b, and the opening and closing main control component 2300a is connected to the clamp head 1200 through the opening and closing control rod body 2300b, so as to control the opening and closing action of the clamp head 1200. Figure 3 As shown, the clamping forceps 1200 may include a fixed clamp 1200a and a movable clamp 1200b, the movable clamp 1200b is rotatably connected to the fixed clamp 1200a, and the distal end of the opening and closing control rod body 2300b is connected to the movable clamp 1200b through the inner cavity of the curved tube section 1120, so as to control the movable clamp 1200b to perform an opening and closing action relative to the fixed clamp 1200a.

[0062] See also Figure 5 and Figure 6 As shown, in one embodiment, the control device 2000 includes a gripping handle 2100, which is mainly used by the operator to perform gripping operations during the operation, and at least one of the bending control component and the opening and closing control component is assembled on the gripping handle 2100. The gripping handle 2100 can be made of an insulating polymer material with a certain strength, such as one or more of polyether block polyamide (PEBAX), polyether ether ketone (PEEK), polyethylene (PE), polypropylene (PP), polyamide (PA), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), etc., or a metal or alloy material with an insulating material plated on the surface can be used, which is not limited here.

[0063] In one embodiment, the gripping handle 2100 is provided with a transfer channel 2100a, which is communicated with the inner cavity of the main body tube section 1110. The gripping handle 2100 is provided with an assembly cavity 2100b, in which at least one of the bending control component and the opening and closing control component is assembled, and the assembly cavity 2100b can be adaptively changed with the structure of the bending control component and the opening and closing control component, which is not limited here.

[0064] The bending main control component 2200a can use a variety of mechanisms to control the bending control line 2200b, for example, Figure 5 As shown, the bending main control component 2200a adopts a rotating knob, and a groove for threadedly assembling the rotating knob is provided in the assembly cavity 2100b. The rotating knob is rotatably assembled in the assembly cavity 2100b, and the rotating knob is wound and connected with the bending control line body 2200b, and is used to rotate and drive the bending control line body 2200b to implement winding and releasing.

[0065] The opening and closing main control component 2300a can use a variety of mechanisms to control the opening and closing control rod body 2300b, for example, Figure 5 As shown, the main opening and closing control component 2300a adopts a push button, and the surface of the push button can be designed with an arc surface and frosted, which is convenient for holding and increasing friction, and is convenient for pushing with the thumb. The opening and closing control rod body 2300b is a rod-shaped structure with a certain flexibility, so that when the push button pushes the opening and closing control rod body 2300b, a push force can be applied to the distal direction through the opening and closing control rod body 2300b, but the part of the opening and closing control rod body 2300b in the curved tube section 1120 can also cooperate with the curved tube section 1120 to form an adaptive angle bend. The flexibility of the opening and closing control rod body 2300b needs to be balanced and constructed according to the application of the push force and the adaptation to the bending of the curved tube section 1120, which is not limited here.

[0066] The push button is connected to a mounting shaft, and the mounting shaft can be equipped with a compression spring with elastic restoring force. The mounting shaft is connected to the opening and closing control rod body 2300b, and the mounting shaft is assembled in the assembly space, so that the push button is elastically assembled in the assembly space through the compression spring and the mounting shaft. The operator pushes the push button to control the opening and closing control rod body 2300b to apply a pushing force toward the distal direction, which is used to control the rotation of the fixed clamp 1200a to implement the opening and closing action. When the operator cancels the force applied to the push button, the compression spring can use the elastic force to pull the opening and closing control rod body 2300b to return toward the proximal direction. The compression spring can be made of medical grade stainless steel, such as 304 stainless steel, 316 stainless steel, 420 stainless steel, 430 stainless steel, etc.

[0067] The grip handle 2100 has a gripping concave surface 2100c suitable for gripping, see Figure 5 and Figure 6 As shown, the holding recessed surface 2100c can be a wave-like surface. The construction of the holding recessed surface 2100c is mainly based on the shape constructed by the operator's multiple fingers in the holding state. For example, the operator's four fingers can form a completely fitting holding contact state with the holding recessed surface 2100c, which is convenient for the operator to hold and conforms to ergonomics. It can solve the disadvantages of existing nasal surgical instruments such as surgical forceps that must be mainly operated by the thumb and index finger, and solve the problems of easy fatigue and easy tissue damage caused by misoperation.

[0068] The surgical instrument system includes an auxiliary device 3000, which is connected to the surgical clamp 1000 and is used to provide at least one of the electrocoagulation function, suction function and flushing function.

The electrocoagulation component 3100b can stop bleeding quickly without leaving seams in the tissue, effectively shortening the operation time. Figure 4 As shown, the unit channel of the clamp tube body 1100 includes an axially penetrating electrocoagulation channel 1110c. For example, the inner cavity of the main tube section 1110 includes an axially penetrating electrocoagulation channel 1110c, and the transmission wire is inserted into the electrocoagulation channel 1110c. The electrocoagulation main control component 3100a is electrically connected to the electrocoagulation component 3100b through the transmission wire. In one embodiment, the electrocoagulation control component includes a temperature sensor 3100c, and the temperature sensor 3100c is arranged on the clamping forceps head 1200.

[0071] The suction tube body 3200b can be a disposable tube, and the length of the suction tube body 3200b can be set according to specific needs. During use, the suction tube body 3200b can be inserted into the suction channel 1110d and extended to the distal end of the suction channel 1110d until the distal end of the suction tube body 3200b reaches the distal end of the clamping forceps head 120. When the holding handle 2100 is provided with a transfer channel 2100a, the transfer channel 2100a is communicated with the inner cavity of the main tube section 1110, that is, the transfer channel 2100a can be communicated with the suction channel 1110d. At this time, the suction tube body 3200b can be inserted with the help of the transfer channel 2100a of the holding handle 2100, and move to the distal end and penetrate into the suction channel 1110d. The material of the suction tube body 3200b can be a polymer material with a certain degree of flexibility, such as polycarbonate (PC), polypropylene (PP), polyethylene (PE) and other materials.

[0073] The flushing tube body can be a disposable tube, and the length of the flushing tube body can be set according to specific needs. During use, the flushing tube body can be inserted into the flushing channel 1110e and extended to the distal end of the flushing channel 1110e until the distal end of the flushing tube body reaches the clamping forceps head 1200. When the holding handle 2100 is provided with a transfer channel 2100a, the transfer channel 2100a is connected to the inner cavity of the main tube section 1110, that is, the transfer channel 2100a can be connected to the flushing channel 1110e. At this time, the flushing tube body can be inserted with the help of the transfer channel 2100a of the holding handle 2100, and move to the distal end and penetrate into the flushing channel 1110e. The material of the flushing tube body can be a polymer material with a certain degree of flexibility, such as polycarbonate (PC), polypropylene (PP), polyethylene (PE) and other materials.

[0074] In one embodiment, the control device 2000 includes a foot controller 4000, and at least one of the electrocoagulation control component, the suction control component, and the flushing control component is connected to the foot controller 4000. The foot controller 4000 can integrate the centralized control of the electrocoagulation function, the suction function, and the flushing function, for example, the suction tube body 3200b and the flushing tube body use the same tube body, or the suction tube body 3200b and the flushing tube body use two tube bodies tied together, or the transmission wire, the suction tube body 3200b, and the flushing tube body are tied together, etc. The foot controller 4000 can be provided with physiological saline required for flushing during surgery, a negative pressure system required for suction, and an electric control and temperature display required for electrocoagulation, etc., which are not limited here.

[0075] In one embodiment, the control device 2000 includes a connection structure 5000, and at least one of the transmission wire, the suction tube body 3200b and the flushing tube body is detachably connected to the foot controller 4000 through the connection structure 5000. The electrocoagulation main control component 3100a, the suction main control component 3200a, and the flushing main control component 3300a can all be in the form of a foot pedal, that is, the electrocoagulation main control component 3100a adopts an electrocoagulation control foot pedal, the suction main control component 3200a adopts a suction control foot pedal, and the flushing main control component 3300a adopts a flushing control foot pedal. The operator can operate with his feet during the operation, which is convenient for freeing the operator's hands and easy to operate.

[0076] Before use, the suction tube body 3200b or the flushing tube body of the required length in the operation is passed through the inner cavity of the main tube section 1110, for example, through the suction channel 1110d or the flushing channel 1110e respectively, until it reaches the clamping forceps head 1200. The specific length can be controlled in advance to solve the problem of improper suction position. At least one of the transmission wire, the suction tube body 3200b and the flushing tube body is detachably connected to the foot controller 4000 through the connecting structure 5000, so that any one of the transmission wire, the suction tube body 3200b and the flushing tube body can be plugged in and out. With the cooperation of the endoscope, the operator holds the gripping handle 2100 of the surgical instrument system and extends the distal end of the surgical instrument system from the patient's nasal cavity or other positions. In this process, according to the patient's lesion position to be reached, the bending angle of the curved tube section 1120 can be adjusted to adapt to the patient's nasal passage.

[0077] When arriving at the patient's site, the operator can use the opening and closing control component to control the clamping forceps head 1200 to perform the opening and closing action, and then clamp the target object at the lesion, such as cysts, polyps, etc. During this process, the electrocoagulation control pedal can be operated at the same time to perform electrocoagulation hemostasis on the area where bleeding is required. When the field of vision is blurred and the lesion needs to be flushed, the suction control pedal and the flushing control pedal can be operated. If the suction tube body 3200b or the flushing tube body is blocked due to long-term use, the suction tube body 3200b or the flushing tube body can be disassembled and replaced with a disposable tube body for continued use. When the operation is completed, the surgical clamp 1000 and the endoscope are withdrawn to complete the operation.
