Examples

As shown in fig. 1-3, the costal cartilage cutting device of the present embodiment includes a cutting knife 10, a connecting rod 20 disposed at one end of the cutting knife 10, a sleeve 23 sleeved on an outer wall of the connecting rod 20, a pair of baffles 24 respectively fixed on two opposite sides of the sleeve 23, and a driving device for driving the sleeve 23 to move along a length direction of the connecting rod 20; the thickness of the connecting rod 20 is less than or equal to that of the cutter 10; the axial direction of the cutter 10 is parallel to the axial direction of the connecting rod 20, and the length direction of the baffle plate 24 is perpendicular to the advancing direction of the cutter 10. Specifically, when the cutting knife is used, firstly, the baffle plate 24 is moved to one end, closest to the cutting knife 10, of the connecting rod 20 through the driving device, then the cutting knife 10 is used for cutting costal cartilage, the length of the cutting knife 10 is short, and due to the blocking of the baffle plate 24 (the baffle plate 24 abuts against the costal cartilage when the cutting knife is used, the cutting knife 10 cannot go deep continuously), the cutting knife 10 only can cut to a small depth once, then the sleeve 23 and the baffle plate 24 are moved for a certain distance through the driving device, the cutting knife continues to cut, at the moment, the cutting knife 10 can cut to a deeper depth, the step is repeated, and finally, the costal cartilage can be completely and safely cut. And because the depth is a little bit deep each time, under the condition that the thickness of costal cartilage is unknown, the depth of one-time cutting can be effectively avoided from being too deep, other tissues can be effectively prevented from being injured, and a patient can be better protected. In addition, the baffle 24 can be adjusted to a proper position at the beginning according to experience and then gradually deepened to improve the operation efficiency.

The driving device in this embodiment includes a first through hole 21 opened inside the connecting rod 20 along the length direction of the connecting rod 20, a second through hole 22 opened on the side wall of the connecting rod 20, a supporting block 25 fixedly disposed inside the sleeve 23, a threaded hole opened on the supporting block 25, a screw 27 inserted into the first through hole 21, and a knob 28 disposed on the outer end of the screw 27 on the connecting rod 20; the second through hole 22 penetrates through the connecting rod 20 and is communicated with the first through hole 21, and the length direction of the second through hole 22 is parallel to the axial direction of the connecting rod 20; the supporting block 25 is slidably arranged in the second through hole 22, and the screw 27 is in threaded connection with the threaded hole. Specifically, by rotating the knob 28, the screw 27 is rotated, and the supporting block 25 screwed to the screw 27 is moved along the length direction of the screw 27, thereby pulling the sleeve 23 and the baffle 24 to move. The thinner threaded rods 27 and the support blocks 25 are only required to provide a positioning function, since the shield 24 is not subjected to a large force during operation. Wherein the end of the screw 27 needs to be rotatably connected with the end of the first through hole 21 to ensure that the screw 27 is not moved when rotating.

The middle part of the side wall of the sleeve 23 in the embodiment is provided with a third through hole 26; the third through hole 26 penetrates the sleeve 23 and corresponds to the second through hole 22; two ends of the supporting block 25 are detachably inserted into the third through hole 26 after respectively passing through the second through hole 22. Specifically, when the device is used, the sleeve 23 is firstly inserted into the connecting rod 20, then the supporting block 25 is inserted into the third through hole 26, and then the screw 27 is screwed into the first through hole 21 and is in threaded connection with the threaded hole of the supporting block 25, so that the device can be assembled (reverse operation is required during disassembly), and each part of the device can be well cleaned and sterilized after the operation is finished.

In this embodiment, the cutting knife further comprises a handle 31 detachably and fixedly connected with one end of the connecting rod 20 far away from the cutting knife 10. The end part of the handle 31 far away from the cutting knife 10 is provided with a pair of clamping blocks 32 and a clamping plate 34; the side wall of one end of the clamping block 32, which is far away from the connecting rod 20, is provided with clamping grooves 33, and the clamping grooves 33 are used for clamping a clamping plate 34; a pair of latch blocks 32 are respectively arranged at two opposite sides of the knob 28; the catch plate 34 abuts the side of the knob 28 remote from the connecting rod 20. Specifically, handle 31 is thicker, is more convenient to hold, need earlier sleeve 23 cover on connecting rod 20 when using, again with handle 31 cover on connecting rod 20, wherein accessible fastening bolt fixes handle 31, also can be interference fit between handle 31 and the connecting rod 20 and come fixed handle 31 temporarily, knob 28 can be restricted well to the fixture block 32 and the draw-in groove 33 of handle 31 tip, avoids it to rock, but can rotate knob 28 and adjust the position of baffle 24. The knob 28 can be blocked only by clamping the clamping plate 34 into the clamping groove 33, and the knob 28 and the screw 27 can be taken out by taking down the clamping plate 34.

The inner wall of the clamping groove 33 in the embodiment is provided with a magnet; the card 34 is made of a metal material that can be attracted by a magnet. Specifically, the clamping plate 34 can be fixed more stably, and slipping caused by shaking in the using process is avoided.

The baffle 24 in this embodiment is located near the end of the connecting rod 20. The length of the second through hole 22 is L, and the length of the sleeve 23 is 2L. In particular, the second through hole 22 can be completely blocked by the sleeve 23, so that liquid is prevented from entering the first through hole 21 in the operation process, and the complexity of cleaning is improved.

In summary, in the costal cartilage cutting device of the present embodiment, when in use, the baffle 24 is moved to the end of the connecting rod 20 closest to the cutting knife 10 by the driving device, and then the cutting knife 10 is used to cut the costal cartilage, because the length of the cutting knife 10 is short, and because the baffle 24 blocks (the baffle 24 abuts against the costal cartilage during cutting, the cutting knife 10 cannot go deep), the cutting knife 10 only cuts to a small depth at one time, and then the sleeve 23 and the baffle 24 are moved by a certain distance by the driving device to continue cutting, at this time, the cutting knife 10 can cut to a deeper depth, and this step is repeated, so that the costal cartilage can be cut completely and safely. And because the depth is a little bit deep each time, under the condition that the thickness of costal cartilage is unknown, the depth of one-time cutting can be effectively avoided from being too deep, other tissues can be effectively prevented from being injured, and a patient can be better protected. In addition, the baffle 24 can be adjusted to a proper position at the beginning according to experience and then gradually deepened to improve the operation efficiency.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
