Description

Technical Field

[0001] This utility model belongs to the field of surgical instrument technology, and in particular to a smoke extractor for easy assembly of surgical instruments. Background Technology

[0002] An ultrasonic surgical scalpel is a surgical instrument that uses an ultrasonic frequency generator to drive the handle and blade to vibrate ultrasonically, thereby performing surgical cutting. During cutting, it breaks the hydrogen bonds in the proteins of the contacting tissue cells and coagulates ruptured blood vessels to stop bleeding, achieving both cutting and closure simultaneously. It boasts advantages such as high reliability and surgical safety, and has a wide range of applications.

[0003] When a scalpel is used, it achieves hemostasis by sintering blood vessel tissue using ultrasound. Therefore, the scalpel blade reaches a relatively high temperature. Furthermore, due to the cavitation effect of ultrasound, a certain amount of smoke and / or gas is generated inside the patient's body during surgery. In laparoscopic surgery, where the space is very confined, even a small amount of smoke or gas can prevent the endoscopic camera from clearly viewing internal structures, which is extremely dangerous in medical procedures. Moreover, the smoke or gas generated during surgery contains many viruses and bacteria, which can easily harm the health of medical personnel and therefore needs to be absorbed.

[0004] For example, in the utility model patent with publication number CN219397470U, although the smoke is absorbed through the air nozzle, the assembly structure between the scalpel and the smoking device is complex and inconvenient to disassemble and replace. Moreover, if any part is damaged, the device cannot be used, resulting in a great waste of resources. Summary of the Invention

[0005] In view of this, the present invention provides a smoke extractor for surgical instruments that is easy to assemble, in order to solve the above problems.

[0006] An easily assembled fumigation device for surgical instruments includes a clamping assembly and a fumigation assembly disposed on the clamping assembly. The fumigation device is mounted on a scalpel, which includes a blade assembly. The clamping assembly includes a clamping member capable of clamping onto the blade assembly, a rotating nut, and a clamping nut disposed on the outside of the clamping member. The clamping member includes a body, a gripper at one end of the body, a stepped portion of the gripper near the fumigation assembly, and a wedge-shaped surface between the gripper and the stepped portion. The rotating nut is screwed onto the clamping member and is used to push the clamping nut toward the fumigation assembly, causing the wedge-shaped surface to contract toward the blade assembly, thereby causing the gripper to abut against and clamp the blade assembly. The fumigation assembly includes a smoke exhaust chamber assembly sleeved on the clamping member, a fumigation tube connected to the smoke exhaust chamber assembly and used to suck up smoke, a locking nut screwed onto the smoke exhaust chamber assembly, and a smoke exhaust tube disposed on the smoke exhaust chamber assembly. The fumigation tube is sleeved on the blade assembly, and the locking nut is used to fix the fumigation tube onto the smoke exhaust chamber assembly. The fumigation tube, the smoke exhaust chamber assembly, and the smoke exhaust tube form a smoke absorption channel for sucking up smoke.

[0007] Furthermore, the clamping member also includes multiple external threads provided on the gripper hand, multiple abutment heads provided on the side of the gripper hand away from the smoking assembly, and two fixing protrusions provided on the body.

[0008] Furthermore, the clamping nut includes an insertion slot for inserting the smoke exhaust chamber assembly, and two opposing fixing grooves, the fixing grooves being adapted to the size and shape of the fixing protrusion.

[0009] Furthermore, the rotating nut includes an internal thread located on the inner sidewall of the rotating nut, the internal thread being used to engage with the external thread to fix the rotating nut relative to the clamping member.

[0010] Furthermore, the smoke exhaust chamber assembly includes a smoke exhaust chamber, a ball bearing located within the smoke exhaust chamber, a backing ring located within the smoke exhaust chamber and used to abut against the ball bearing, and a sealing assembly located within the smoke exhaust chamber and connected to the backing ring.

[0011] Furthermore, the smoke exhaust chamber is used to connect the smoke extraction tube, the smoke exhaust tube, and to accommodate the ball bearing, the abutment ring, and the sealing assembly. The smoke exhaust chamber includes an abutment located inside the smoke exhaust chamber, a connector located outside the smoke exhaust chamber, and an internal thread located inside the smoke exhaust chamber. A stepped protrusion is also provided at the end of the smoke extraction tube.

[0012] Furthermore, the abutment includes a first abutment groove for abutting the outer ring of the ball bearing, a second abutment groove spaced apart from the first abutment groove and used to abut the abutment ring, and a third abutment groove spaced apart from the second abutment groove and used to abut the sealing assembly.

[0013] Furthermore, the connector includes a pipe connector disposed on the side wall of the exhaust chamber and a plug connector disposed at one end of the exhaust chamber.

[0014] Furthermore, the sealing assembly is used to prevent smoke from leaking from the gap between the blade assembly and the end of the smoking tube to improve the airtightness of the entire smoking device. It includes a sealing ring fitted over the outside of the blade assembly and a sealing gasket located on the side of the sealing ring facing the smoking tube.

[0015] Furthermore, the locking nut is used to fix the smoking pipe in the smoke exhaust chamber, and it includes an externally threaded end provided on the outer side wall of the locking nut, and a stepped edge that protrudes towards the smoking pipe.

[0016] Compared with existing technologies, the present invention provides an easily assembled fumigation device for surgical instruments. The fumigation tube and the exhaust tube are connected via the exhaust chamber, forming a flow channel for removing smoke. Furthermore, through the cooperation of the clamping member and the clamping nut, simply rotating the rotating nut towards the fumigation tube pushes the clamping nut, allowing the gripper to hold the scalpel assembly. Reverse rotation of the rotating nut releases the gripper assembly, facilitating assembly and replacement of the scalpel assembly with the fumigation device. The ball bearings ensure that when the scalpel assembly is rotated according to surgical needs, the movement of the clamping member and the exhaust chamber is separated by the inner and outer bearing rings, ensuring that the exhaust chamber does not rotate with the clamping member, thus facilitating the normal operation of the surgery and improving the operator's user experience.

[0025] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0026] like Figures 1 to 8 The diagram shows a structural schematic of an easily assembled fumigation device for surgical instruments provided by this utility model. The easily assembled fumigation device for surgical instruments includes a clamping assembly 10 and a fumigation assembly 20 disposed on the clamping assembly 10. The easily assembled fumigation device for surgical instruments also includes other functional modules, such as an airflow regulating mechanism connected to the easily assembled fumigation device for surgical instruments, and a negative pressure device for absorbing gas, etc., which should be known to those skilled in the art and will not be described in detail here.

[0027] like Figure 1As shown, the easily assembled fumigation device for surgical instruments can be mounted on a scalpel 100. The scalpel 100 can be an ultrasonic scalpel, an electrosurgical cutter, etc. In this embodiment, the scalpel 100 is an ultrasonic scalpel, which includes a blade assembly 101 for inserting into the human body to perform surgical operations, and a handle 102 connected to the blade assembly 101 and used to control the rotation direction of the blade assembly 101. The scalpel 100 itself is prior art and will not be described in detail here.

[0028] like Figure 2 As shown, the clamping assembly 10 includes a clamping member 11 that can clamp onto the cutter bar assembly 101, and a rotating nut 12 and a clamping nut 13 disposed outside the clamping member 11.

[0029] like Figure 5 As shown, the clamping member 11 is used to clamp the scalpel handle assembly 101 to fix the smoking device to the scalpel 100. The clamping member 11 includes a body 111, a gripper 112 disposed at one end of the body 111, multiple external threads 113 disposed on the gripper 112, multiple abutment heads 114 disposed on the side of the gripper 112 away from the smoking assembly 20, a stepped portion 115 disposed on the side of the gripper 112 near the smoking assembly 20, and two fixing protrusions 116 disposed on the body 111. The clamping member 11 can be made of elastic materials such as plastic and is integrally molded.

[0030] The gripper 112 is used to grip the tool bar assembly 101 in conjunction with the clamping nut 13. Its specific working principle will be described below in conjunction with the clamping nut 113.

[0031] The external thread 113 is used to couple with the rotating nut 12, and its specific working principle will be described below in conjunction with the internal thread 121.

[0032] The abutment head 114 is used to prevent the rotating nut 12 from disengaging from the clamping member 11 after the gripper hand 112 has passed through the clamping nut 13 and the rotating nut 12. When there is no external force, the gripper hand 112 is in a naturally open state due to its elasticity. During assembly, the abutment head 114 can be clamped with a clamping tool to retract the gripper hand 112, thereby facilitating the passage of the clamping member 11 through the clamping nut 13 and the rotating nut 12 during assembly.

[0033] The stepped portion 115 is used to restrict the position of the ball bearing 212 described below in the arrangement direction of the clamping nut 13 and the rotating nut 12, and it will be described below together with the ball bearing 212.

[0034] The fixed protrusion 116 is used to limit the clamping nut 13 to prevent the clamping nut 13 from rotating with the rotating nut 12.

[0035] A wedge-shaped surface 117 is also provided between the gripper 112 and the stepped portion 115. The outer diameter of the gripper 112 is smaller than the outer diameter of the stepped portion 115, thus forming the wedge-shaped surface 117. In use, when the rotating nut 12 is tightened, the rotating nut 12 will push the clamping nut 13 to move. At this time, the clamping nut 13 will slide on the wedge-shaped surface 117, thereby forcing the gripper 112 to retract inward until the gripper 112 clamps the tool bar assembly 101. At this time, the tool bar assembly 101 is fixed to the clamping member 11.

[0036] like Figure 6 As shown, the rotating nut 12 is screwed onto the clamping member 11. In use, it slides against the clamping nut 13 on the side facing the smoking assembly 20 to clamp the clamping member 11. It includes an internal thread 121 on the inner sidewall of the rotating nut 12.

[0037] The internal thread 121 is used to mate with the external thread 113 to screw the rotating nut 12 onto the clamping member 11. When the rotating nut 12 is mounted on the clamping member 11 and the internal thread 121 engages with the external thread 113, the two can be relatively fixed together.

[0038] like Figure 7 As shown, during use, the inner wall of the clamping nut 13 abuts against the wedge-shaped surface 117 of the clamping member 11, causing the gripper 112 to retract inward, thereby fixing the clamping member 11 onto the knife bar assembly 101. The clamping nut 13 includes an insertion slot 131 for avoiding the smoke exhaust chamber 211, and two opposing fixing grooves 132. The insertion slot 131 is used for insertion with the corresponding structure of the smoke extraction assembly 20, which will be described in detail below.

[0039] The fixing groove 132 is used to engage with the fixing protrusion 116 to prevent the clamping nut 13 from rotating with the rotating nut 12. Therefore, the fixing groove 132 and the fixing protrusion 116 are matched in size and shape.

[0040] like Figure 3As shown, the smoking assembly 20 includes a smoke exhaust chamber assembly 21 sleeved on the clamping member 11, a smoking pipe 22 connected to the smoke exhaust chamber assembly 21 and used to suck up smoke, a locking nut 23 screwed on the smoke exhaust chamber assembly 21, and a smoke exhaust pipe 24 disposed on the smoke exhaust chamber assembly 21.

[0041] like Figure 2 As shown, the smoke exhaust chamber assembly 21 includes a smoke exhaust chamber 211, a ball bearing 212 located in the smoke exhaust chamber 211, a push ring 213 located in the smoke exhaust chamber 211 and used to push against the ball bearing 14, and a sealing assembly 214 located in the smoke exhaust chamber 211 and connected to the push ring 213.

[0042] like Figure 8 As shown, the exhaust chamber 211 is used to connect the smoke extraction pipe 22, the exhaust pipe 24, and to accommodate the ball bearing 212, the abutment ring 213, and the sealing assembly 214, etc. The exhaust chamber 211 includes an abutment 215 located inside the exhaust chamber 211, a connector 216 located outside the exhaust chamber 211, and an internally threaded portion 217 located inside the exhaust chamber 211.

[0043] The abutment top 215 includes a first abutment groove 2151 for abutting the outer ring of the ball bearing 212, a second abutment groove 2152 spaced apart from the first abutment groove 2151 and used for abutting the abutment ring 213, and a third abutment groove 2153 spaced apart from the second abutment groove 2152 and used for abutting the sealing assembly 214.

[0044] The first abutment groove 2151, the second abutment groove 2152, and the third abutment groove 2153 are all annular grooves formed inside the smoke exhaust chamber 211, with their centers located on the same straight line. Furthermore, along the arrangement direction of the first abutment groove 2151, the second abutment groove 2152, and the third abutment groove 2153, the inner circumference of each groove increases sequentially to accommodate their respective functions.

[0045] The connector 216 includes a pipe connector 2161 disposed on the side wall of the smoke exhaust chamber 211, and a plug connector 2162 disposed at one end of the smoke exhaust chamber 211.

[0046] The pipe joint 2161 is used to quickly connect the smoke exhaust chamber 211 to the smoke exhaust pipe 24.

[0047] The connector 2162, which is an annular flange, facilitates the quick positioning of the exhaust chamber 211 onto the clamping nut 13. When the connector 2162 is inserted into the insertion slot 131 of the clamping nut 13, the exhaust chamber 211 and the clamping nut 13 are relatively fixed. The connector 2162 also improves the connection strength between the two to prevent the exhaust chamber 211 from deviating axially during use.

[0048] The internal thread portion 217 is used to assemble the locking nut 23 to fix the locking nut 23 to the smoke exhaust chamber 211.

[0049] like Figure 2 As shown, the ball bearing 212 is a prior art technology, comprising an inner bearing ring 2121 and an outer bearing ring 2122. The ball bearing 212 is used to ensure that the exhaust chamber 211 does not rotate when the tool holder assembly 101 rotates.

[0050] The inner bearing ring 2121 is sleeved and fixed on the stepped portion 115 and is abutted by the stepped portion 115.

[0051] The outer bearing ring 2122 is abutted against the exhaust chamber 211 by the abutment ring 213. When the scalpel 100 needs to rotate according to actual needs, that is, when the scalpel shaft assembly 101 needs to be rotated, the clamping member 11 rotates accordingly, thereby driving the inner bearing ring 2121 to rotate. The outer bearing ring 2122 remains fixed on the exhaust chamber 211 and does not rotate, thus keeping the position of the exhaust pipe 24 relatively fixed and preventing it from rotating with the rotation of the scalpel 100. This prevents the exhaust pipe 24 from getting caught in the user's hand, improving the user's experience.

[0052] like Figure 2 As shown, the sealing assembly 214 is used to prevent smoke from leaking from the gap between the blade assembly 101 and the end of the smoke tube 22, thereby improving the airtightness of the entire smoker. It includes a sealing ring 2141 fitted over the blade assembly 101 and a sealing gasket 2142 located on the side of the sealing ring 2141 facing the smoke tube 22. Both the sealing ring 2141 and the sealing gasket 2142 are annular components, meaning that both have through holes on their inner sides for the blade assembly 101 to pass through.

[0053] The sealing ring 2141 is made of elastic material such as silicone, and it fits tightly against the outer wall of the blade assembly 101 to prevent inhaled smoke from leaking from the gap between the end of the smoking tube 22 and the blade assembly 101, thereby affecting the normal use of the smoking device. Two spaced-apart sealing lips 2143 are also provided on the through hole of the sealing ring 2141 for the blade assembly 101 to pass through. The diameter of the sealing lip 2143 is smaller than the outer diameter of the blade assembly 101, so that when the blade assembly 101 passes through the through hole, the sealing lip 2143 will deform, thereby strengthening the seal.

[0054] The sealing gasket 2142 is located between the sealing ring 2141 and the smoke pipe 22, that is, the end of the smoke pipe 22 abuts against the sealing gasket 2142 to prevent smoke from leaking from its end. When the locking nut 23 is tightened on the smoke exhaust chamber 211, it will tightly press the end of the smoke pipe 22 against the sealing ring 2141 to prevent leakage.

[0055] In use, the smoking tube 22 is sleeved on the outside of the scalpel assembly 101 and inserted into the patient's body together with the scalpel assembly 101 to suck up the fumes generated during surgical cutting. Its other end is inserted into the exhaust chamber 211 so that the fumes are discharged by the exhaust pipe 24. The smoking tube 22 and the scalpel assembly 101 are spaced apart to form a flow channel for fumes to circulate. Multiple exhaust holes 221 for fumes to circulate are provided on the side wall of the end of the smoking tube 22 connected to the exhaust chamber 211. The end of the smoking tube 22 also has a stepped protrusion 222, which cooperates with the locking nut 23 to fix the smoking tube 22 in the exhaust chamber 211.

[0056] The locking nut 23 is used to fix the smoking pipe 22 in the exhaust chamber 211. It includes an externally threaded end 231 on the outer wall of the locking nut 23 and a stepped edge 232 facing the smoking pipe 22. Specifically, the minimum inner diameter of the stepped edge 232 of the locking nut 23 is approximately equal to the outer diameter of the stepped protrusion 222 of the smoking pipe 22, while the maximum inner diameter is larger than the outer diameter of the stepped protrusion 222. When the locking nut 23 is screwed into the exhaust chamber 211 with a wrench, it is fixedly connected within the exhaust chamber 211. Simultaneously, the stepped edge 232 of the locking nut 23 abuts against the stepped protrusion 222 of the smoking pipe 22, thereby fixing the smoking pipe 22 within the exhaust chamber 211. Meanwhile, one end of the ball bearing 212, the abutment ring 213, and the sealing assembly 214 are abutted by the smoke exhaust chamber 211, and the other end is abutted and fixed by the end of the locking nut 23, thereby fixing the ball bearing 212, the abutment ring 213, the sealing assembly 214, and the smoke tube 22 in the smoke exhaust chamber 211.

[0057] like Figure 3 As shown, one end of the exhaust pipe 24 is inserted into the pipe joint 2161, and the other end is connected to a negative pressure device (not shown) to collect and discharge the smoke absorbed by the smoke pipe 22.

[0058] The negative pressure device can be a negative pressure pump, which is existing technology and will not be described in detail here. The negative pressure device is used to keep the entire flue pipe 21 under negative pressure during operation, thereby facilitating the absorption of smoke. A flow channel is formed between the smoke inlet pipe 22, the smoke outlet chamber 211, and the smoke outlet pipe 24 to remove smoke.

[0059] The smoking pipe 22, the exhaust chamber 211, the exhaust pipe 24, the sealing assembly 214, the knife rod assembly 101, and the locking nut 23 form a sealed cavity within the exhaust chamber 211 for the flow of smoke. After entering the smoking pipe 22, the smoke flows through this sealed cavity into the exhaust pipe 24 and then out.

[0060] During assembly, first insert the ball bearing 212 into one end of the smoke exhaust chamber 211, and then use a clamping device to reduce the size of the abutment head 114 to insert the clamping member 11 so that it passes through the inner bearing ring 2121. Next, insert the abutment ring 213, the sealing ring 2141, and the sealing gasket 2142 in sequence. Then, put the locking nut 23 on the outside of the smoke extraction tube 22 and screw it into the smoke exhaust chamber 211. Finally, use the clamping device to reduce the size of the abutment head 114 so that the clamping nut 13 and the rotating nut 12 pass through the clamping member 11 in sequence and are fixed on the clamping member 11. Finally, insert the smoke exhaust tube 24 into the pipe joint 2161 so that the smoke exhaust tube 24 is fixed on the smoke exhaust chamber 211. At this time, the smoke extractor is assembled.

[0061] In use, simply pass the blade assembly 101 through the clamping member 11, then rotate the rotating nut 12 to push the clamping nut 13 so that the gripper 112 clamps the blade assembly 101 for surgery. During surgery, the rotation angle of the blade assembly 101 can be adjusted as needed via the handle 102. The clamping member 11 rotates accordingly, causing the inner bearing ring 2121 to rotate, while the outer bearing ring 2122 remains fixed to the exhaust chamber 211 and does not rotate. After use, simply rotate the rotating nut 12 outwards so that the wedge-shaped surface 117 gradually withdraws from contact with the inner wall of the clamping nut 13. The gripper 112 then gradually opens outwards to release its grip on the blade assembly 102, thus completing the disassembly of the fumigation device and the scalpel 100. This smoking device not only allows for quick assembly and pairing with the scalpel 100, but also enables the scalpel 100 to be reused multiple times by assembling the scalpel 100 and the smoking device separately, thereby reducing medical costs and improving the patient's medical experience.

[0062] Compared with the prior art, the facilitating fumigation device for surgical instruments provided by this utility model connects the fumigation tube 22 and the exhaust tube 24 through the exhaust chamber 211, thereby forming a flow channel for sucking away smoke. Furthermore, through the cooperation of the clamping member 11 and the clamping nut 13, simply rotating the rotating nut 12 towards the fumigation tube 22 pushes the clamping nut 13, causing the gripper 112 to clamp the blade assembly 101. Rotating the rotating nut 12 in the opposite direction releases the gripper 112 from the blade assembly 101, facilitating the assembly and replacement of the blade assembly 101 with this fumigation device. Furthermore, the ball bearing 212 allows the movement of the clamping member 11 and the smoke exhaust chamber 211 to be separated by the inner bearing ring 2121 and the outer bearing ring 2122 when the blade assembly 101 is rotated according to surgical needs. This ensures that the smoke exhaust chamber 211 will not rotate with the clamping member 11, thereby facilitating the normal operation of the surgery and improving the user experience for the operator.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
