技术领域technical field
本发明涉及一种医用手术缝合针。The invention relates to a medical surgical suture needle.
背景技术Background technique
现有的手术缝合针都为弯针，在有些手术场合如五官科的鼻中隔创口缝合时就需要把弯针用外力变直，外力变直后其可能并不是很直从而会影响手术效果，另外外力变直还容易导致手术过程中的断针可能，增加手术风险。The existing surgical suture needles are all curved needles. In some surgical occasions, such as the suture of nasal septum wounds in ENT, it is necessary to straighten the curved needle with external force. After the external force is straightened, it may not be very straight, which will affect the surgical effect. Straightening by external force can also easily lead to the possibility of broken needles during the operation, increasing the risk of the operation.

针对上述技术问题，本发明的目的是提供一种手术效果好，不易产生断针风险的医用手术缝合针。In view of the above technical problems, the purpose of the present invention is to provide a medical surgical suture needle with good surgical effect and less risk of needle breakage.
为解决上述技术问题，本发明采用以下技术方案：一种医用手术缝合针，包括针和线，针为直型空心管状，包括针头斜端面、底端面、针头斜端面和底端面之间的中间针管部，在底端面设有切槽导入口，中间针管部还设有上下切槽，切槽导入口与上下切槽的上端相联通，上下切槽设有上大下小的收紧斜角和卡紧细槽，所述卡紧细槽联通所述收紧斜角的下方末端，线从切槽导入口的外端进入上下切槽的上端、上下切槽的收紧斜角、卡紧固定在上下切槽的卡紧细槽处。In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a medical surgical suture needle, including a needle and a thread, the needle is a straight hollow tube, including a needle inclined end surface, a bottom end surface, and an intermediate area between the needle head inclined end surface and the bottom end surface. The needle tube part is provided with a slotting inlet on the bottom surface, and the middle needle tube part is also provided with upper and lower slots. The slotting inlet is connected with the upper end of the upper and lower slots. and the clamping thin groove, the clamping thin groove communicates with the lower end of the tightening bevel, the wire enters the upper end of the upper and lower cutting grooves from the outer end of the groove introduction port, the tightening bevel of the upper and lower cutting grooves, and the clamping It is fixed at the fastening thin groove of the upper and lower cut grooves.
本发明提供的一种医用手术缝合针的有益效果是：由于包括针和线，针为直型空心管状，包括针头斜端面、底端面、针头斜端面和底端面之间的中间针管部，在底端面设有切槽导入口，中间针管部还设有上下切槽，切槽导入口与上下切槽的上端相联通，上下切槽设有上大下小的收紧斜角和卡紧细槽，所述卡紧细槽联通所述收紧斜角的下方末端，线从切槽导入口的外端进入上下切槽的上端、上下切槽的收紧斜角、卡紧固定在上下切槽的卡紧细槽处，因此,该手术针是完全直的，无需拉直，而且线合理地卡紧固定在针上，使用非常方便。The beneficial effect of a medical surgical suture needle provided by the present invention is: since it includes a needle and a thread, the needle is a straight hollow tube, including the inclined end surface of the needle head, the bottom end surface, and the intermediate needle tube part between the inclined end surface and the bottom end surface of the needle head. The bottom end surface is provided with a grooved inlet, and the middle needle tube is also provided with an upper and lower groove. The grooved inlet is connected with the upper end of the upper and lower grooves. groove, the clamping thin groove communicates with the lower end of the tightening bevel, the wire enters the upper end of the upper and lower slits from the outer end of the slit inlet, the tightening bevels of the upper and lower slits are clamped and fixed on the upper and lower slits Therefore, the surgical needle is completely straight without straightening, and the thread is reasonably clamped and fixed on the needle, which is very convenient to use.
进一步地，上下切槽的卡紧细槽边缘设有内翻夹持片，所述内翻夹持片包含支点边和转动边，所述支点边和卡紧细槽边缘相联，所述转动边远离卡紧细槽边缘，相面对的两片内翻夹持片的支点边之间的距离略大于转动边之间的距离。该内翻夹持片使得卡紧固定在卡紧细槽处的线被可靠地夹压在相对的内翻夹持片之间，并且在有外力将线向外拉动时，线会带动相贴紧的内翻夹持片微小向外翻动，使得线在卡紧细槽处被夹压固定得更紧更稳定。Further, the edge of the clamping slot of the upper and lower cut grooves is provided with an inturned clamping piece, and the inturned clamping piece includes a fulcrum side and a rotating side, and the fulcrum side is connected with the edge of the clamping slot, and the rotating side The sides are away from the edge of the clamping slot, and the distance between the fulcrum sides of the two facing inward-turning clamping pieces is slightly greater than the distance between the turning sides. The inverting clamping piece makes the thread clamped and fixed at the clamping slot be reliably clamped between the opposite inverting clamping pieces, and when the thread is pulled outward by an external force, the thread will be brought into contact with each other. The tight inward-turning clamping piece is slightly turned outward, so that the thread is clamped and fixed at the clamping slot to be tighter and more stable.
进一步地，线上设有辅助定位结，该辅助定位结设置在空心针管内的前后两处卡紧细槽之间。Further, an auxiliary positioning knot is provided on the wire, and the auxiliary positioning knot is arranged between the front and rear two fastening thin grooves in the hollow needle tube.

为了使得本发明实现的技术手段，创新特征与功能易于了解，下面将进一步阐述本发明。In order to make the technical means, innovative features and functions realized by the present invention easy to understand, the present invention will be further described below.
本发明提供的一种医用手术缝合针，包括针和线，针为直型空心管状，包括针头斜端面1、底端面2、针头斜端面1和底端面2之间的中间针管部3，在底端面2设有切槽导入口4，中间针管部3还设有上下切槽5，切槽导入口4与上下切槽5的上端相联通，上下切槽5设有上大下小的收紧斜角6和卡紧细槽7，所述卡紧细槽7联通所述收紧斜角6的下方末端，线从切槽导入口4的外端进入上下切槽5的上端、上下切槽5的收紧斜角6、卡紧固定在上下切槽5的卡紧细槽7处，并且在上下切槽5的卡紧细槽7边缘设有内翻夹持片8，所述内翻夹持片8包含支点边8A和转动边8B，所述支点边8A和卡紧细槽7边缘相联，所述转动边8B远离卡紧细槽7边缘，相面对的两片内翻夹持片8的支点边8A之间的距离略大于转动边8B之间的距离，为了使针线更有效地避免脱离，可在线上设有辅助定位结9，该辅助定位结9设置在空心针管内的前后两处卡紧细槽7之间。A medical surgical suture needle provided by the present invention includes a needle and a thread. The needle is a straight hollow tube, including a needle inclined end face 1, a bottom end face 2, and an intermediate needle tube part 3 between the needle head inclined end face 1 and the bottom end face 2. The bottom end surface 2 is provided with a slotting inlet 4, and the middle needle tube part 3 is also provided with an upper and lower slotting slot 5. The slotting inlet 4 communicates with the upper end of the upper and lower slotting slots 5. Tighten the bevel 6 and tighten the narrow groove 7, the clamping thin groove 7 is connected to the lower end of the tightened bevel 6, and the line enters the upper end of the upper and lower cutting groove 5 from the outer end of the groove introduction port 4, and the upper and lower cutting grooves are connected to each other. The tightening bevel 6 of the slot 5 is clamped and fixed at the clamping slot 7 of the upper and lower slots 5, and an inward clamping piece 8 is provided on the edge of the clamping slot 7 of the upper and lower slots 5, and the inner The flip clamping piece 8 includes a fulcrum side 8A and a rotating side 8B, the fulcrum side 8A is connected to the edge of the clamping slot 7, the rotating side 8B is far away from the edge of the clamping slot 7, and the two facing pieces are turned inward. The distance between the fulcrum sides 8A of the clamping piece 8 is slightly greater than the distance between the rotating sides 8B. In order to prevent the needle thread from breaking away more effectively, an auxiliary positioning knot 9 can be provided on the line, and the auxiliary positioning knot 9 is arranged on the hollow needle. Between the front and rear two clamping slots 7 in the pipe.
前面所述的实施方案使得这种医用手术缝合针具有结构简单、手术创伤少、成本低、穿线方便、针线不易脱离、多重卡位方式即通过细槽卡位或内翻片卡位或定位结卡位防止针线脱离的优点。The aforementioned embodiment makes this medical surgical suture needle have simple structure, less surgical trauma, low cost, convenient threading, needle and thread are not easy to disengage, and multiple locking methods, that is, through fine groove locking or inverting plate locking or positioning knots. The card position prevents the advantage of the needle and thread from falling out.
此外，由于本技术方案的针体上的切槽导入口4设置在底端面2，使得切槽导入口4和上下切槽5的设置对针体的强度和牢固度的影响变得最小，使用时在产生前面所述优点和便利的同时，挂线位置与以往手术针较一致让医生感觉比较适应。In addition, since the groove introduction port 4 on the needle body of this technical solution is arranged on the bottom end surface 2, the influence of the setting of the groove introduction port 4 and the upper and lower grooves 5 on the strength and firmness of the needle body becomes minimal, and the use While producing the above-mentioned advantages and convenience, the thread-hanging position is more consistent with the previous surgical needle, which makes the doctor feel more comfortable.
