Description

Technical Field

[0001] This invention relates to the field of laser scalpel technology, and more particularly to a contact laser scalpel that is easy to control in terms of speed. Background Technology

[0002] Laser scalpels utilize the highly concentrated energy of lasers as surgical "knife" in surgical procedures. Compared to traditional scalpels, laser scalpels are sharper, easily cutting through skin, muscle, and bone, thus leading to their widespread development.

[0003] Currently, laser scalpels have evolved from the initial non-contact laser scalpels to contact laser scalpels. Contact laser scalpels can directly contact the patient's muscles and other tissues during use, thereby improving the surgeon's handling experience.

[0004] However, in actual use, the surgeon must make sure the process of using the round blade to stop bleeding is short, otherwise it will have an ablation effect and cause rebleeding. Therefore, it is necessary to control the contact time between the round blade and the patient's muscles and other tissues.

[0005] However, the actual environment is complex, especially since folds can easily appear on the cut tissue, and bleeding blood vessels can easily be buried in the folds. If the contact time between the round blade and the fold is too short, it will not be able to achieve the purpose of hemostasis. If the contact time between the round blade and the fold is too long, ablation will occur, causing rebleeding and causing unnecessary harm to the patient. Summary of the Invention

[0006] In view of this, and in view of the shortcomings of the prior art, the present invention provides a contact laser scalpel that is easy to control speed, so as to solve the problems mentioned in the background art.

[0007] The present invention provides a contact laser surgical scalpel that is easy to control speed, comprising a connector and a blade head mounted at the bottom end of the connector, and support components symmetrically arranged on both sides of the blade head;

[0008] The support component includes a spreading part, which is inclined in a vertically upward direction. The top end of the spreading part is movably connected to the connector, and the bottom end of the spreading part can make circular motion in a vertical plane with its top end as the center.

[0009] The height of the bottom end of the spreading part is lower than the height of the bottom end of the cutter head;

[0010] The bottom end of the expansion portion contacts the human tissue S. When the blade head is pushed down, the downward movement of the blade head drives the bottom ends of the two expansion portions to gradually move away from each other, so as to flatten the wrinkled human tissue S.

[0011] Preferably, the plane where the bottom end of the cutter head is located is a first plane, and the plane where the bottom end of the spreading part is located is a second plane, wherein the first plane and the second plane are parallel to each other, and the first plane is located above the second plane.

[0012] Preferably, the support assembly further includes a fixing part that is fixedly connected to the connector. The fixing part includes a fixing seat, a groove is provided on the bottom end surface of the fixing seat, a pin is fixed inside the groove, a sleeve is rotatably sleeved on the outside of the pin, and the top end of the expansion part is fixedly connected to the sleeve.

[0013] Preferably, the inner top wall of the groove is a top stop surface, and a bottom stop rod is fixed inside the groove. The opening part penetrates the gap between the top stop surface and the bottom stop rod, so that the included angle between the opening part and the axial direction of the cutter head is within the range of 45-80°.

[0014] Preferably, the fixing part further includes a fixing plate and a reinforcing rib. The fixing plate and the reinforcing rib are both fixed to the upper surface of the fixing seat. There are two reinforcing ribs, and an intermediate groove is formed between the two reinforcing ribs. The fixing plate is fixed to the joint by fasteners.

[0015] Preferably, the spreading part includes a connecting rod and a support rod, the top end of the connecting rod is hinged to the joint by means of a sleeve and a pin, and the bottom end of the connecting rod is fixedly connected to the support rod.

[0016] Preferably, a safety rod is fixedly connected to the outer surface of the end of the connecting rod away from the support rod, and both ends of the support rod and the safety rod are connected by an arc-shaped rod.

[0017] Preferably, the fixed base is provided with an elastic support portion at the end away from the connecting rod. The elastic support portion includes a first magnet and a second magnet, wherein the first magnet is fixed on the connecting rod, the second magnet is disposed inside the fixed base, and the same magnetic poles of the first magnet and the second magnet are arranged opposite each other.

[0018] Preferably, the fixing base has a screw hole that connects the groove and the intermediate groove. The screw hole is threaded to an outer sleeve. The bottom surface of the outer sleeve has a blind hole. The second magnet is fixedly connected to the inside of the blind hole. The top surface of the outer sleeve has a hexagonal protrusion, which is coaxially arranged with the outer sleeve.

[0019] Compared with related technologies, the contact laser surgical scalpel provided by this invention, which facilitates speed control, has the following beneficial effects:

[0020] (1) By symmetrically arranging two inclined support parts on both sides of the blade head, when the blade head is pushed down, the downward movement of the blade head can drive the bottom ends of the two support parts to gradually move away, thereby flattening the folded human tissue S and exposing the bleeding site buried in the fold. Then, the blade head is used to stop the bleeding. The entire hemostasis process can be achieved simply by moving the blade head. The operation is simple. At the same time, the entire hemostasis process is short, making it easy to control the speed and improve the actual hemostasis efficiency. Moreover, since the support parts are set on both sides of the blade head, the distance between them and the human tissue S is short, so that the distance between the bottom ends of the two inclined support parts can be kept at a small size to achieve the purpose of opening the fold. This is conducive to reducing the size of the entire support component and making it easy to use in small space environments.

[0021] (2) By setting the first magnet and the second magnet, and setting the same magnetic poles of the first magnet and the second magnet opposite to each other, the first magnet and the second magnet generate a repulsive force between like poles. In this way, the supporting part can be pressed against the bottom stop bar without the action of external force, ensuring that the two support bars maintain the minimum distance before contacting the human tissue S.

[0022] (3) By installing the second magnet in the outer sleeve and then connecting the outer sleeve to the screw hole, the distance between the first magnet and the second magnet can be adjusted by rotating the outer sleeve, that is, the magnitude of the force between the first magnet and the second magnet can be adjusted.

[0023] (4) Using fasteners to install the fixing plate on the side of the connector can increase the roughness of the side of the connector. Since the main body and the connector are connected by threads, the roughness of the connector surface can make the connector more secure during installation so that the connector can be tightened onto the main body.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] Please see Figures 1 to 9 This invention provides a contact laser scalpel with easy speed control. Similar to existing technologies, the scalpel mainly comprises four parts: a main body 100, an optical fiber 200, a connector 300, and a blade head 400. The main body 100 and the connector 300 are connected by a matching external thread head 101 and an internal thread hole 301. In this embodiment, the external thread head 101 and the internal thread hole 301 are located on the main body 100 and the connector 300, respectively. The optical fiber 200 and the blade head 400 are connected by coupling.

[0037] The present invention differs from the prior art in that:

[0038] like Figure 1As shown, two support components 500 are symmetrically arranged on both sides of the blade head 400. The function of these support components 500 is to flatten the folded human tissue S and directly expose the bleeding site buried inside the fold, so that the blade head 400 can stop the bleeding at the bleeding site.

[0039] like Figure 4 As shown, the support assembly 500 includes a spreading part 520, which is inclined. Specifically, the distance between the two spreading parts 520 gradually decreases in the vertically upward direction. The top of the spreading part 520 is hinged to the connector 300. The bottom of the spreading part 520 can make circular motion in the vertical plane with its top as the center. Specifically, the spreading part 520 can make circular motion in the plane formed by the axis of the blade head 400 and the axis of the spreading part 520. In this way, when the bottom of the spreading part 520 contacts the human tissue S and gradually presses against the human tissue S, the bottom of the two spreading parts 520 will gradually open outward, thereby flattening the wrinkled human tissue S and preventing the bleeding site from being buried inside the wrinkles.

[0040] like Figure 3 As shown, the bottom of the spreading part 520 is at a lower height than the bottom of the blade head 400. Specifically, the plane where the bottom of the blade head 400 is located is the first plane 401, and the plane where the bottom of the spreading part 520 is located is the second plane 501. The first plane 401 and the second plane 501 are parallel to each other, and the first plane 401 is located above the second plane 501. The purpose of this arrangement is that before the blade head 400 contacts the human tissue S, the bottom of the spreading part 520 will contact the human tissue S first. As the blade head 400 moves toward the human tissue S, the bottom of the two spreading parts 520 can spread open the wrinkled human tissue S by the movement of the blade head 400.

[0041] The bottom end of the spreading part 520 contacts the human tissue S. When the blade head 400 is pushed down, the downward movement of the blade head 400 drives the bottom ends of the two spreading parts 520 to gradually move away from each other, so as to flatten the wrinkled human tissue S.

[0042] In the above scheme, by symmetrically arranging two inclined supporting parts 520 on both sides of the blade head 400, when the blade head 400 is pushed down, the downward movement of the blade head 400 can drive the bottom ends of the two supporting parts 520 to gradually move away, thereby flattening the wrinkled human tissue S and exposing the bleeding site buried in the wrinkles. Then, the blade head 400 is used to stop the bleeding at the bleeding site. The entire hemostasis process can be achieved simply by moving the blade head 400, which is simple to operate. At the same time, the entire hemostasis process is short, making it easy to control the speed and improve the actual hemostasis efficiency. Moreover, since the supporting parts 520 are located on both sides of the blade head 400, the distance between them and the human tissue S is short, so that the distance between the bottom ends of the two inclined supporting parts 520 can be kept at a small size to achieve the purpose of opening up the wrinkles. This is beneficial to reduce the size of the entire support component 500 and facilitates use in small space environments.

[0043] like Figure 4 and Figure 5 As shown, the support assembly 500 also includes a fixing part 510 fixedly connected to the connector 300. The fixing part 510 includes a fixing seat 513. A groove 5131 is provided on the bottom surface of the fixing seat 513. From the overall perspective, the fixing seat 513 forms an inverted U-shaped structure after the groove 5131 is provided. A pin 517 is fixed inside the groove 5131. A sleeve 516 is rotatably sleeved on the outside of the pin 517. The top end of the expansion part 520 is fixedly connected to the sleeve 516, that is, the expansion part 520 can rotate around the pin 517 as the center.

[0044] like Figure 5 , Figure 6 and Figure 8As shown, the inner top wall of the groove 5131 is a top stop surface 5132, and a bottom stop rod 5133 is fixed inside the groove 5131. The spreading part 520 penetrates the gap between the top stop surface 5132 and the bottom stop rod 5133, so that the included angle between the spreading part 520 and the axial direction of the cutter head 400 is within the range of 45-80°. Specifically, the top stop surface 5132 is used to limit the maximum angle between the spreading part 520 and the axial direction of the cutter head 400. When the spreading part 520 contacts the stop surface 5132, the spreading part 520 is at its maximum tilt angle. The bottom stop rod 5133 is used to limit the minimum angle between the spreading part 520 and the axial direction of the cutter head 400. When the spreading part 520 contacts the bottom stop rod 5133, the spreading part 520 is at its minimum tilt angle. In this embodiment, the maximum tilt angle of the spreading part 520 is 80° and the minimum tilt angle is 45°. The purpose of this setting is that when the spreading part 520 is at its minimum tilt, after the spreading part 520 comes into contact with the human tissue S, the angle between the bottom end of the spreading part 520 and the human tissue S is also approximately 45°. At this angle, the force of the cutting head 400 transmitting the force of pressing the human tissue S onto the spreading part 520 can be converted into a force that drives the bottom ends of the two spreading parts 520 away from each other. The purpose of setting the maximum tilt angle of the spreading part 520 to 80° is that when the spreading part 520 is in this angle state, the spreading part 520 will not cause any adverse effects such as obstruction of the hemostasis action of the cutting head 400.

[0045] like Figure 5 As shown, the fixing part 510 also includes a fixing plate 511 and a reinforcing rib 514. The fixing plate 511 and the reinforcing rib 514 are both fixed to the upper surface of the fixing base 513. The reinforcing rib 514 can improve the structural strength of the fixing plate 511, so that the fixing plate 511 will not bend easily and has good stability. There are two reinforcing ribs 514, and a middle groove 515 is formed on the top of the fixing base 513. The fixing plate 511 is fixed to the connector 300 by fasteners 512. In this embodiment, the fasteners 512 are countersunk screws. The side of the fixing plate 511 that contacts the connector 300 is an arc-shaped surface 5111. The center of the arc-shaped surface 5111 is located on the axis of the connector 300. That is, the part of the arc-shaped surface 5111 that contacts the connector 300 can fit completely with the connector 300.

[0046] Using fasteners 512 to install the fixing plate 511 on the side of the connector 300 can increase the roughness of the side of the connector 300. Since the main body 100 and the connector 300 are connected by threads, the roughness of the surface of the connector 300 can make the connector 300 more firmly gripped during installation so that the connector 300 can be tightened onto the main body 100.

[0047] like Figure 4 and Figure 7As shown, the expansion part 520 includes a connecting rod 521 and a support rod 522. The top end of the connecting rod 521 is hinged to the connector 300. Specifically, the top end of the connecting rod 521 is fixedly connected to the sleeve 516, and the bottom end of the connecting rod 521 is fixedly connected to the support rod 522. The connecting rod 521 and the support rod 522 are arranged perpendicular to each other. The support rod 522 is mainly used to increase the contact area between the support rod 522 and the human tissue S, and to avoid the bottom end of the support rod 522 damaging the human tissue S.

[0048] To prevent the axial ends of the support rod 522 from scratching human tissue S, this embodiment uses a safety rod 523 that is parallel to the support rod 522 and fixed to the connecting rod 521. Then, arc-shaped rods 524 are fixedly connected to both ends of the support rod 522. The end of the arc-shaped rod 524 away from the support rod 522 is then fixedly connected to the end of the safety rod 523. Overall, the support rod 522, the safety rod 523, and the two arc-shaped rods 524 work together to form a square ring structure, which makes the overall structure smoother and prevents scratching of human tissue S.

[0049] like Figure 6 , Figure 8 and Figure 9 As shown, an elastic support portion 530 is provided between the fixed base 513 and the connecting rod 521. The elastic support portion 530 includes a first magnet 531 and a second magnet 532. The first magnet 531 is fixed on the connecting rod 521, and the second magnet 532 is disposed on the fixed base 513. The same magnetic poles of the first magnet 531 and the second magnet 532 are arranged opposite each other.

[0050] In the above scheme, by setting the first magnet 531 and the second magnet 532, and setting the same magnetic poles of the first magnet 531 and the second magnet 532 opposite to each other, the first magnet 531 and the second magnet 532 generate a repulsive force between like poles. In this way, the supporting part 520 can be pressed against the bottom stop bar 5133 without the action of external force, ensuring that the two support bars 522 maintain a minimum distance before contacting the human tissue S.

[0051] Then, to facilitate adjustment of the distance between the first magnet 531 and the second magnet 532, a screw hole 533 is provided on the fixing base 513, which connects the groove 5131 and the intermediate groove 515. The screw hole 533 is internally threaded to the outer sleeve 534. A blind hole 5341 is provided on the bottom surface of the outer sleeve 534, and the second magnet 532 is fixed inside the blind hole 5341. A rotating structure is provided on the top surface of the outer sleeve 534 to facilitate the rotation of the outer sleeve 534. The rotating structure can be a cross groove or a hexagonal groove, etc. In this embodiment, the rotating structure is preferably a hexagonal protrusion 535 provided on the top surface of the outer sleeve 534. The hexagonal protrusion 535 is coaxially arranged with the outer sleeve 534. In use, a hexagonal sleeve that matches the hexagonal protrusion 535 can be used to put on the hexagonal protrusion 535, and then the hexagonal sleeve can be used to drive the outer sleeve 534 to rotate.

[0052] By installing the second magnet 532 in the outer sleeve 534 and then threading the outer sleeve 534 into the screw hole 533, the distance between the first magnet 531 and the second magnet 532 can be adjusted by rotating the outer sleeve 53, which means adjusting the magnitude of the force between the first magnet 531 and the second magnet 532.

[0053] The working principle of the contact laser surgical scalpel with easy speed control provided by this invention is as follows:

[0054] When in use, the surgeon holds the main body 100 to move the position of the blade 400;

[0055] Under normal conditions, since the same magnetic poles of the first magnet 531 and the second magnet 532 are arranged opposite each other, a repulsive force is generated between the like poles. Furthermore, since the second magnet 532 is mounted on the fixed base 513, and the fixed base 513 is fixedly connected to the connector 300 via the fixed plate 511 and fasteners 512, the repulsive force between the like poles of the first magnet 531 and the second magnet 532 cannot push the second magnet 532 to move. However, since the first magnet 531 is fixed to the connecting rod 521, and the top end of the connecting rod 521 is hinged to the fixed base 513 via the sleeve 516 and the pin 517, and the connecting rod 521 can move between the top stop surface 5132 and the bottom stop rod 5133, the first magnet 531 and the second magnet 532... The repulsive force between the like poles will push the connecting rod 521 against the bottom stop rod 5133. In other words, the distance between the bottom ends of the two opening parts 520 can remain unchanged without external force. Of course, the position of the second magnet 532 can also be adjusted to adjust the magnitude of the repulsive force between the like poles of the first magnet 531 and the second magnet 532. The specific adjustment method is as follows: the hexagonal protrusion 535 can be turned by using the hexagonal cylinder that matches the hexagonal protrusion 535. Since the hexagonal protrusion 535 and the outer sleeve 534 are arranged coaxially and the hexagonal protrusion 535 is fixedly connected to the outer sleeve 534, the outer sleeve 534 will rotate with the hexagonal protrusion 535. Since the outer sleeve 534 is threadedly connected to the screw... The distance between the outer sleeve 534 and the first magnet 531 changes as the outer sleeve 534 rotates. This means the distance between the second magnet 532 and the first magnet 531, both installed inside the outer sleeve 534, also changes. The greater the distance between the first magnet 531 and the second magnet 532, the smaller the repulsive force between their like poles; conversely, the smaller the distance, the greater the repulsive force. After adjusting the magnitude of the repulsive force, the blade 400 can be used for hemostasis. The specific operating steps are: keep the direction of movement of the blade 400 as perpendicular as possible to the surface of the tissue to be hemostaticated, and then gradually move the blade 400 towards the tissue. Since the first plane 401 is located above the second plane 501, the support rod 522 on the spreading part 520 will first contact the tissue to be hemostaticated, and then the blade head 400 will continue to move downward. At this time, the support rod 522 will increase the friction between itself and the tissue to be hemostaticated as the blade head 400 moves downward. On the other hand, since the angle between the spreading part 520 and the blade head 400 is in the range of 45-80°, the distance between the two support rods 522 will gradually increase. When there are wrinkles on the surface of the tissue to be hemostaticated, the two support rods 522 will flatten the wrinkles and completely expose the area to be hemostaticated. Then the blade head 400 will contact the area to be hemostaticated to achieve the purpose of hemostasis. Of course, the hemostasis time needs to be short to avoid rebleeding.After hemostasis is achieved, move the blade head upwards by 400 degrees. At this point, the repulsive force between the like poles of the first magnet 531 and the second magnet 532 will press the connecting rod 521 back against the bottom stop rod 5133, ready for the next hemostasis operation.
