Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and in particular to a spinal endoscope bone surface hemostasis device. Background Art

[0002] During spinal surgery, since the operation involves cutting bones, bleeding is inevitable. In order to effectively control the bleeding, bone wax is often used to stop the bleeding during surgery.

[0003] Currently, the conventional hemostasis method is to evenly apply a layer of bone wax on the end of a slender cylindrical tool, and then accurately deliver it to the bleeding site in the surgical field of view, using the adhesion and sealing properties of bone wax to block the blood vessels and achieve the purpose of hemostasis.

[0004] However, during endoscopic spinal surgery, blood and other tissue fluids must be continuously flushed out with water to maintain a clear view. Bone wax is easily impacted by the water flow during transport, causing it to fall off or shift, making hemostasis extremely difficult. This not only increases the complexity of the surgery but also potentially compromises both the outcome and the patient's recovery.

[0005] Therefore, how to effectively implement bone wax hemostasis while ensuring a clear endoscopic field of view has become an urgent problem to be solved in the field of spinal surgery. Utility Model Content

[0065] The spinal endoscopic bone surface hemostasis device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] Reference Figures 1 to 4 As shown, the spinal endoscopic bone surface hemostasis device provided according to an embodiment of the present invention includes a conveying member 10, a pushing member 20 and a limiting member 30.

[0067] The conveying member 10 includes a sleeve member 101 , a conveying tube 102 and a first holding arm 103 . The conveying tube 102 is connected to the front end of the sleeve member 101 , and the first holding arm 103 is connected to the bottom surface of the sleeve member 101 .

[0068] The pushing member 20 includes a connector 201, a pushing rod 202 and a second holding arm 203. The connector 201 is inserted into the sleeve member 101 from the rear end of the sleeve member 101 and can slide along the length direction of the sleeve member 101. One end of the pushing rod 202 is connected to the front end of the connector 201, and the other end passes through the sleeve member 101 and extends into the delivery tube 102. The second holding arm 203 is arranged on the bottom surface of the connector 201.

[0069] The limiting member 30 is connected between the first holding arm 103 and the second holding arm 203 . The limiting member 30 is a telescopic structure with an adjustable telescopic stroke, so as to limit the depth of the connector 201 inserted into the sleeve 101 .

[0070] When the push rod 202 is in its initial state, the end of the push rod 202 is retracted within the delivery tube 102, leaving a space inside the front end of the delivery tube 102 for filling with bone wax. To seal the bleeding, simply pinching the first gripping arm 103 and the second gripping arm together moves the connector 201 and the push rod 202 forward, pushing the bone wax out of the space and sealing it at the bleeding site.

[0071] Based on the above, through the design of the conveying member 10 and the pushing member 20, bone wax can be accurately delivered to the bleeding site, improving the accuracy and efficiency of hemostasis. The design of reserving an accommodating space inside the front end of the conveying tube 102 allows the bone wax to be protected during the conveying process, preventing it from being washed away during the water flushing process, ensuring that the bone wax can reach and stay at the bleeding point. The retractable structure and adjustable retractable stroke of the limiting member 30 allow the doctor to adjust the delivery amount of bone wax according to the specific needs of the operation, increasing the flexibility of the operation, improving the safety of the operation process, and reducing the uncertainty factors in the operation.

[0072] Preferably, in an embodiment of the present invention, the limiting member 30 includes a first column 301 , a second column 302 , an adjustment ring 303 and a spring member 304 .

[0073] The first column 301 is connected to the first holding arm 103 , and a socket 3011 is defined at the end of the first column 301 .

[0074] The second column 302 is connected to the second holding arm 203 , and an end of the second column 302 is inserted into the insertion hole 3011 .

[0075] One end of the adjustment ring 303 is sleeved on the second column 302 and can rotate along the axis of the first column 301 . The other end of the adjustment ring 303 is connected to the outer surface of the first column 301 and can be adjusted along the length direction of the second column 302 .

[0076] The spring member 304 is sleeved on the second column 302 and located between the adjustment ring 303 and the second holding arm 203 .

[0077] In this way, through the design of the adjustment ring 303, the telescopic stroke of the limiting member 30 can be accurately adjusted, thereby accurately controlling the pushing distance of the push rod 202, ensuring that the bone wax can be accurately filled to the required hemostasis position, and the plug-in structure of the first column 301 and the second column 302, as well as the application of the spring member 304, can maintain the stability of the limiting member 30 and prevent accidental movement during surgical operations, and the spring member 304 can push the push rod 202 to reset after use.

[0078] Preferably, in an embodiment of the present invention, the second column 302 includes a first connecting portion 3021 and a second connecting portion 3022 .

[0079] The first connecting portion 3021 is connected to the second holding arm 203 , and the spring member 304 is sleeved on the first connecting portion 3021 .

[0080] The second connection portion 3022 is connected to the front end of the first connection portion 3021 , and the end of the second connection portion 3022 is inserted into the insertion hole 3011 .

[0081] The first connection portion 3021 is provided with a first limiting portion 3023 at the connection with the second column. The first limiting portion 3023 extends circumferentially along the first connection portion 3021. The adjustment ring 303 is sleeved on the first connection portion 3021 and is restricted on the first column by the first limiting portion 3023.

[0082] In this way, the adjustment ring 303 is restricted on the first connection part 3021 by the first limit part 3023, and the insertion depth of the second connection part 3022 can be more accurately controlled, thereby improving the accuracy of bone wax delivery. The separate design of the first connection part 3021 and the second connection part 3022 makes the adjustment operation of the adjustment ring 303 more intuitive and convenient, and the doctor can quickly adjust to the required bone wax delivery amount.

[0083] Preferably, in one embodiment of the present invention, a second limiting portion 3024 is provided at the end of the second connecting portion 3022 , and the second limiting portion 3024 extends circumferentially along the second connecting portion 3022 , and the second limiting portion 3024 is located in the insertion hole 3011 .

[0084] A third limiting portion 3025 is provided on the inner wall of the insertion hole 3011 . The third limiting portion 3025 extends circumferentially along the insertion hole 3011 to limit the second limiting portion 3024 within the insertion hole 3011 .

[0085] In this way, the coordinated use of the second limiting portion 3024 and the third limiting portion 3025 can effectively prevent the second connecting portion 3022 from slipping out of the insertion hole 3011, thereby ensuring the stability and reliability of the operation.

[0086] Preferably, in one embodiment of the present invention, the surface of the first column 301 is provided with an external thread, the inner wall of the adjusting ring 303 is provided with an internal thread, and the adjusting ring 303 is adjustably connected to the first column 301 through the cooperation between the external thread and the internal thread.

[0087] Thus, through the cooperation of the external and internal threads, the adjustment ring 303 can be moved very finely along the axis of the first column 301, thereby achieving precise adjustment of the insertion depth of the second connecting portion 3022. The threaded connection is more secure than a simple sliding connection, ensuring that the adjustment ring 303 will not accidentally slip or loosen after adjustment, and will maintain the set position.

[0088] Preferably, in an embodiment of the present invention, the connector 201 includes a plug-in portion 2011 and a tailstock 2012 .

[0089] The plug-in portion 2011 is inserted into the sleeve member 101 .

[0090] The tailstock 2012 is connected to the rear end of the plug-in portion 2011 , and the second holding arm 203 is connected to the bottom surface of the tailstock 2012 . The diameter of the tailstock 2012 is greater than the diameter of the sleeve 101 .

[0091] In this way, since the diameter of the tail stock 2012 is larger than that of the sleeve member 101, it can serve as a physical limit to prevent the plug-in portion 2011 from being over-inserted into the sleeve member 101, thereby protecting the internal structure from damage. At the same time, when the tail stock 2012 is attached to the tail end of the sleeve member 101, it indicates that the bone wax in the accommodating cavity has been completely pushed out, so that medical staff can make accurate judgments during operation.

[0092] Preferably, in an embodiment of the present invention, a plurality of scale lines 2013 are provided on the surface of the plug-in portion 2011 , and the plurality of scale lines 2013 are distributed at intervals along the length direction of the plug-in portion 2011 .

[0093] In this way, the scale line 2013 provides an intuitive depth indication. The doctor can accurately control the depth of the insertion of the plug-in portion 2011 into the sleeve member 101 by observing the scale line 2013, thereby accurately controlling the amount of bone wax delivered.
