This handle joint 13 is a conventional structure of an existing liposuction needle, and the details are not repeated here.

[0041] like Figure 1As shown, the opening of the V-shaped groove 12 is opened away from the axial second end of the liposuction needle body 1. When the axial first end of the liposuction needle body 1 is inserted into the connective tissue of the bag of wealth, the V-shaped groove 12 can be inserted while cutting the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue. When the axial first end of the liposuction needle body 1 is inserted into the connective tissue of the bag of wealth, the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue have been cut by the V-shaped groove 12. After that, negative pressure is applied by the syringe to quickly suck out the fat in the bag of wealth, and the liposuction is thorough, which can improve the surgical effect of the liposuction needle.

[0042] In this embodiment, Figure 1 As shown, the first axial end side wall of the liposuction needle body 1 is preferably provided with a plurality of liposuction holes 11 spaced apart along the axial direction of the liposuction needle body 1, and the axis of any liposuction hole 11 is arranged at an acute angle α to the axial direction of the liposuction needle body 1, and the position of the acute angle α is as shown in FIG.

[0047] Embodiment 2

[0048] In order to further improve the liposuction effect of the gynecological bag, this embodiment proposes an instrument system for the gynecological bag surgery, which includes, in addition to the above-mentioned liposuction needle 100 for the gynecological bag surgery, a crushing drill needle 2. The crushing drill needle 2 is used in conjunction with the liposuction needle 100 for the gynecological bag surgery. The crushing drill needle 2 is used to cut and crush the connective tissue of the gynecological bag before the liposuction needle liposuctions. Figure 3-Figure 6 As shown, the crushing drill needle 2 includes a solid needle body 21, and the first end 211 of the solid needle body 21 is provided with a shovel-shaped cutting groove 22 opened along the axial direction of the solid needle body 21. The second end 212 of the solid needle body 21 is used to be connected to an electric drill, and the electric drill is used to drive the solid needle body 21 to rotate around the axial direction of the solid needle body 21. The shovel-shaped cutting groove 22 is cut along a smooth curve by a corresponding processing tool (existing tool) from the side wall of the solid needle body 21 to the end of the first end 211 thereof. The shovel-shaped cutting groove 22 is used to insert into the follicle tissue, and the part of the solid needle body 21 except the shovel-shaped cutting groove 22 is generally located outside the human body. Figure 3-Figure 5As shown, the end of the shovel-shaped cutting slot 22 is also formed with a groove 221. The groove 221, as the end structure of the shovel-shaped cutting slot 22, has the function of facilitating insertion and penetrating the skin tissue structure, and can guide the shovel-shaped cutting slot 22 to be inserted into the connective tissue of the gynecomastia. Since the solid needle body 21 is a solid structure, it is heavy and has a stable center of gravity. When the electric drill drives it to rotate, it ensures that the solid needle body 1 rotates around its own axis, and avoids the first end 211 of the solid needle body 21 from producing a conical rotation, forming a hole expansion trend and damaging human tissue. The two side edges of the shovel-shaped cutting slot 22 formed by cutting at the end of the solid needle body 21 are often sharp and have a cutting effect. Especially when the first end 211 of the solid needle body 21 is inserted into the connective tissue of the gynecomastia, the two side edges of the shovel-shaped cutting slot 22 can provide an axial cutting force along the axial direction of the solid needle body 21 to axially cut the connective tissue, thereby playing a role in preliminarily destroying the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue. When the shovel-shaped cutting groove 22 is inserted into the connective tissue of the gynecomastia, the electric drill can be started to drive the solid needle body 21 to rotate around the axis of the solid needle body 21. At this time, the edge positions on both sides of the shovel-shaped cutting groove 22 can also provide a first rotational cutting force around the axis of the solid needle body 21, which plays a role in rotationally cutting the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue. Figure 3-Figure 5As shown, in order to enhance the crushing effect of the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the follicle stimulating body, the present embodiment also provides cutting grooves on both side edge positions of the shovel-shaped cutting groove 22. When the electric drill drives the solid needle body 21 to rotate around the axial direction of the solid needle body 21, the cutting grooves can provide a second rotational cutting force around the axial direction of the solid needle body 21, so as to cut the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the follicle stimulating body together with the first rotational cutting force, so as to achieve the purpose of deeply crushing the connective tissue of the follicle stimulating body, so as to crush the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the follicle stimulating body into small particle structures, and subsequently, a liposuction needle can be directly inserted into the area cut and crushed by the solid needle body 21 to directly aspirate the crushed colloidal or solid matrix, filamentous fibers and fat. The pulverizing drill needle 2 for the operation of the pouch of the present invention is provided with a shovel-shaped cutting groove 22 and a cutting notch on the solid needle body 21, and the solid needle body 21 is driven to rotate by an electric drill, so that the colloid or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the pouch of the present invention can be fully cut and pulverized before liposuction, so that the dense fat piles in the connective tissue of the pouch of the present invention are destroyed and small particles are formed for easy absorption. Subsequently, the liposuction needle 100 for the operation of the pouch of the present invention can be used to directly absorb the fat in the pouch of the present invention. Since the liposuction needle 100 used for the operation on pouches of pouches can further cut and crush the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of pouches of pouches through the V-shaped groove 12 during the insertion process, the crushing effect of the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of pouches ...

[0049] In this embodiment, two or more cutting grooves are formed on both sides of the shovel-shaped cutting groove 22. Generally, the number of cutting grooves on both sides of the shovel-shaped cutting groove 22 is the same, and the cutting grooves on both sides of the shovel-shaped cutting groove 22 are arranged at intervals and staggered in the axial direction of the solid needle body 21. Figure 3-Figure 5 As shown, taking the example of two cutting slots on both sides of the shovel-shaped cutting slot 22, the two cutting slots on one side of the shovel-shaped cutting slot 22 are cutting slot 1 23 and cutting slot 2 24, and the two cutting slots on the other side of the shovel-shaped cutting slot 22 are cutting slot 3 25 and cutting slot 4 26. Figure 5 and Figure 6As shown, the cutting slot 3 25, the cutting slot 1 23, the cutting slot 4 26 and the cutting slot 2 24 are arranged in sequence from the first end 211 to the second end 212 of the solid needle body 21, and there is no axial overlap between adjacent slots. The cutting slot 3 25, the cutting slot 1 23, the cutting slot 4 26 and the cutting slot 2 24 are arranged in an axially spaced and staggered manner along the solid needle body 21, which is conducive to increasing the contact area between the cutting surface of the shovel-shaped cutting chute 22 and the connective tissue of the follicle, thereby enhancing the rotary cutting and crushing effect and cutting efficiency of the connective tissue of the follicle.

[0050] In this embodiment, in order to enhance the crushing effect, it is preferred to further grind the edge positions on both sides of the shovel-shaped cutting groove 22 and the groove edge positions of any cutting groove to form a blade structure, thereby improving the overall sharpness of the shovel-shaped cutting groove 22 and thereby improving the crushing effect of the shovel-shaped cutting groove 22.

[0051] In this embodiment, it is preferred that any one of the cutting grooves 23, 25, 24 and 26 is a circular arc groove, and any two cutting grooves are the same size, and the groove depth of any one of the cutting grooves, the maximum projection length h on the axial section of the solid needle body 21 is 1 / 4 to 1 / 3 of the diameter of the solid needle body 21; the aforementioned axial section is a section through the central axis of the solid needle body 21. Considering that the circular arc groove is located on the side wall of the solid needle body 21, and the side wall of the solid needle body 21 is an arc surface, the circular arc groove is also in the shape of an arc as a whole, and the groove depth of the circular arc groove should also be the length of the arc line, but the maximum projection of the groove depth arc line on the axial section of the solid needle body 21 is a straight line, and the length is h. Generally, it is preferred that h is 1 / 3 of the diameter of the solid needle body 21.

[0052] In this embodiment, Figure 5As shown, the shovel-shaped cutting chute 22 is the main cutting section on the solid needle body 21, and its axial length should not be too long, which is conducive to realizing the small-range precise point cutting of the shovel-shaped cutting chute 2, and avoiding the shovel-shaped cutting chute 22 being too long, causing unnecessary crushing and cutting of tissues that do not need to be cut. Generally, the axial length D1 of the shovel-shaped cutting chute 22 is preferably 2.5 cm, and the corresponding total axial length D2 of the solid needle body 21 is 25 cm. Considering that the main crushing effect on the shovel-shaped cutting chute 22 is the section with the cutting notch, at the same time, considering the precise point cutting of the position to be crushed, the entire section with the cutting notch should be as close as possible to the front end (i.e., the groove 221) of the shovel-shaped cutting chute 22, and generally, the cutting notch at the end of the axial direction of the shovel-shaped cutting chute 22, i.e., the end of the cutting notch 24, is preferably located at a distance D3 of 1.5 cm from the front end (i.e., the front bottom end of the groove 21) of the shovel-shaped cutting chute 22. Based on this, the section where the cutting groove is set can be controlled within 1.5 cm of the front end of the solid needle body 21, so that the crushing section of the solid needle body 21 can achieve precise point cutting of the parsley tissue on the basis of ensuring the crushing effect.

[0053] Furthermore, if Figure 5 As shown, the distance a between the front end of the cutting groove located at the axial front end of the shovel-shaped cutting groove 2, i.e., the cutting groove 3 5, and the rear top end of the groove 21 is generally not greater than the distance x between adjacent cutting grooves, for example, x is 0.3 cm and a is 0.2 cm.

[0054] In this embodiment, Figure 5 As shown, any of the above cutting grooves are semicircular grooves, the diameter of any semicircular groove is d, and the interval x between any two adjacent cutting grooves is generally preferably not less than the diameter d of the semicircular groove. For example, d is 0.3 cm, and x is also 0.3 cm.

[0055] The above-mentioned crushing drill needle 2 for the operation of the gynecomastia is generally used in connection with an electric drill, the solid needle body 21 is used as a drill bit structure, and its second end 212 is configured as a connection structure adapted to be connected with the electric drill, and the connection structure is generally a cylinder coaxial with the solid needle body 21. The electric drill can actually adopt an existing electric solid bone drill.

[0056] In this embodiment, it is preferred that the diameter of the solid needle body 21 is equal to the diameter of the liposuction needle body 1 , for example, the diameter of the solid needle body 21 and the diameter of the liposuction needle body 1 are both 3 mm.

[0057] The following is a detailed description of the method and principle of use of the instrument system for the aortic surgery in this embodiment.

[0058] First, the area to be operated on is anesthetized. Then the first end 211 of the crushing drill needle 2, i.e. the shovel-shaped cutting slot 22, is inserted into and penetrates the connective tissue of the shovel-shaped cutting slot 22. During the entry of the shovel-shaped cutting slot 22, the colloid or solid matrix, filamentous fibers and dense fat piles in the connective tissue can be initially cut and destroyed axially through the two side edge positions of the shovel-shaped cutting slot 22. After the shovel-shaped cutting slot 22 is inserted into the connective tissue of the shovel-shaped cutting slot 22, the electric drill connected to the second end 212 of the solid needle body 21 is started, and the solid needle body 21 is driven to rotate around the axis of the solid needle body 21 at a certain speed (the size is adjusted according to the actual surgical needs, but the rotation speed will not cause damage to the human body). At this time, the two sides of the shovel-shaped cutting slot 22 The edge position provides a first rotational cutting force around the axis of the solid needle body 21, which plays a role in rotationally cutting the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue. At the same time, the cutting groove 1 23, cutting groove 3 25, cutting groove 24 and cutting groove 4 26 on the shovel-shaped cutting groove 22 can provide a second rotational cutting force around the axis of the solid needle body 21, so as to cut the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the rich bag together with the first rotational cutting force, so as to achieve the purpose of deeply crushing the connective tissue of the rich bag, so as to crush the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the rich bag into small particle structures.

[0059] After the grinding drill needle 2 has finished grinding the connective tissue of the operation site of the gynecological bag, the grinding drill needle 2 is withdrawn from the operation site of the gynecological bag, and then the liposuction needle body 1 connected to the syringe is inserted into the area cut and ground by the solid needle body 21. Since the liposuction needle 100 used for the gynecological bag operation can further cut and grind the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the gynecological bag through the V-shaped groove 12 during the insertion process, the grinding effect of the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the gynecological bag can be improved, and the matrix, fiber or fat pile that is not cut and ground by the solid needle body 21 can be avoided, so as to ensure that the liposuction needle 100 used for the gynecological bag operation can easily and thoroughly suck fat, thereby basically all the connective tissue of the gynecological bag is sucked out, and the problem of unevenness after liposuction and local tissue being pulled and damaged by suction can be avoided. The above-mentioned syringe connected to the liposuction needle body 1 generally uses a 20ml syringe.

[0060] The instrument system for the operation of the gynecological bag proposed in this embodiment, by simultaneously providing the crushing drill needle 2 and the liposuction needle 100 for the operation of the gynecological bag, can firstly use the crushing drill needle 2 to fully cut and crush the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the gynecological bag before liposuction, so that the dense fat piles in the connective tissue of the gynecological bag are destroyed and formed into small particles that are easy to absorb, and then use the liposuction needle 100 for the operation of the gynecological bag of embodiment 1 to directly absorb the fat in the gynecological bag.

Among the water injection holes 31, the end of the water injection hole located at the axial end of the water injection needle 31 is not more than 2 cm away from the axial front end of the aforementioned inclined surface structure of the water injection needle 31. At the same time, the end of the water injection hole located at the axial end of the water injection needle 31 is not more than 0.5 cm away from the axial front end of the aforementioned inclined surface structure of the water injection needle 31. As a preferred solution, the above b2 = 2 cm, b1 = 0.5 cm. By concentrating the water injection holes 31 near the axial first end of the water injection needle 3, it is beneficial to realize the small-range point water injection at the axial first end of the water injection needle 3, thereby improving the water injection accuracy and water injection effect.

[0064] In this embodiment, at least one of a water injection syringe, a liposuction syringe and an electric drill is also included, wherein the water injection syringe is detachably connected to the threaded head 321 of the water injection needle connector 32, the liposuction syringe is detachably connected to the handle connector 13, and the electric drill is detachably connected to the second end 212 of the solid needle body 21. The electric drill can be an electric solid bone drill. The water injection syringe and the liposuction syringe are both existing conventional syringes, and their specific structures and working principles are not repeated here. In general, it is preferred that the water injection syringe, the liposuction syringe and the electric drill are configured simultaneously in the instrument system used for the operation of the rich bag.

[0065] The following is a detailed description of the method and principle of use of the instrument system for the aortic valve surgery in this embodiment.

[0066] First, the axial first end of the water injection needle 3 connected to the water injection syringe is inserted into the operation site of the gynecological bag, and the gynecological bag operation site is injected with water for anesthesia. After the water injection is completed, the water injection needle 3 is removed from the gynecological bag site to wait for the anesthesia to take effect.

[0067] After the anesthesia takes effect, the first end 211 of the crushing drill needle 2, that is, the shovel-shaped cutting groove 22, is inserted into and penetrates the connective tissue of the pouch. During the entry of the shovel-shaped cutting groove 22, it can perform preliminary axial cutting and destruction on the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue through the edge positions on both sides of the shovel-shaped cutting groove 22. After the shovel-shaped cutting groove 22 is inserted into the connective tissue of the pouch, the electric drill connected to the second end 212 of the solid needle body 21 is started to drive the solid needle body 21 to rotate around the axial direction of the solid needle body 21 at a certain speed (the size is adjusted according to the actual surgical needs, but the rotation speed will not cause damage to the human body). At this time, the shovel-shaped cutting groove 22 The edge positions on both sides provide a first rotational cutting force around the axis of the solid needle body 21, which plays a role in rotationally cutting the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue. At the same time, the cutting groove 1 23, cutting groove 3 25, cutting groove 24 and cutting groove 4 26 on the shovel-shaped cutting groove 22 can provide a second rotational cutting force around the axis of the solid needle body 21, so as to cut the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the rich bag together with the first rotational cutting force, so as to achieve the purpose of deeply crushing the connective tissue of the rich bag, so as to crush the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the rich bag into small particle structures.

[0068] After the grinding drill needle 2 has finished grinding the connective tissue of the operation site of the gynecological bag, the grinding drill needle 2 is withdrawn from the operation site of the gynecological bag, and then the liposuction needle body 1 connected to the syringe is inserted into the area cut and ground by the solid needle body 21. Since the liposuction needle 100 used for the gynecological bag operation can further cut and grind the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the gynecological bag through the V-shaped groove 12 during the insertion process, the grinding effect of the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the gynecological bag can be improved, and the matrix, fiber or fat pile that is not cut and ground by the solid needle body 21 can be avoided, so as to ensure that the liposuction needle 100 used for the gynecological bag operation can easily and thoroughly suck fat, thereby basically all the connective tissue of the gynecological bag is sucked out, and the problem of unevenness after liposuction and local tissue being pulled and damaged by suction can be avoided. The above-mentioned syringe connected to the liposuction needle body 1 generally uses a 20ml syringe.

[0069] The instrument system for the operation of the gynecological bag proposed in this embodiment, by simultaneously providing the crushing drill needle 2 and the liposuction needle 100 for the operation of the gynecological bag, can firstly use the crushing drill needle 2 to fully cut and crush the colloidal or solid matrix, filamentous fibers and dense fat piles in the connective tissue of the gynecological bag before liposuction, so that the dense fat piles in the connective tissue of the gynecological bag are destroyed and formed into small particles that are easy to absorb, and then use the liposuction needle 100 for the operation of the gynecological bag of embodiment 1 to directly absorb the fat in the gynecological bag. During the insertion process, the V-shaped groove 12 can further cut and crush the colloidal or solid matrix, filamentous fibers and dense fat deposits in the connective tissue of the pouch, thereby improving the crushing effect of the colloidal or solid matrix, filamentous fibers and dense fat deposits in the connective tissue of the pouch before liposuction, ensuring that the liposuction needle 100 used for the pouch surgery can completely suck fat, thereby basically all the connective tissue of the pouch can be sucked out, avoiding the problems of unevenness after liposuction and local tissue being pulled and damaged by suction, thereby improving the effect of pouch liposuction surgery and user experience.

[0070] In addition, the instrument system for the operation of the pimple of the present embodiment is also equipped with a water injection needle 3 for anesthesia, which is used together with the aforementioned crushing drill needle 2 and the liposuction needle 100 for the operation of the pimple of the present embodiment, so that the functional facilities of the instrument system for the operation of the pimple of the present embodiment are more complete, which is conducive to the smooth progress of the operation process of crushing the pimple first and then liposuction, thereby improving the user experience and the surgical effect; at the same time, by setting the distance from the end of the water injection hole 31 located at the axial end of the water injection needle 3 in any row of water injection holes 31 to no more than 2 cm from the axial first end of the water injection needle 3, it is conducive to realizing small-range point water injection at the axial first end of the water injection needle 3, thereby improving the accuracy and effect of water injection.

[0071] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
