[0023] Reference Figure 1-3 As shown, it is a preferred embodiment provided by the utility model.

[0024] The hand-held hysteroscopic tissue removal tool comprises an instrument body 1, a rotary cutting tube 2 and an anti-slip part 3. The instrument body 1 and the rotary cutting tube 2 are assembled, and the rotary cutting tube 2 is used for tissue removal in the uterine cavity; the instrument body 1 comprises a gripping portion 11, and the anti-slip part 3 is assembled and arranged flat with the gripping portion 11. The anti-slip part 3 has a first anti-slip area 31 and a second anti-slip area 32, and the first anti-slip area 31 and the second anti-slip area 32 are respectively used to enhance the gripping force, and the first anti-slip area 31 and the second anti-slip area 32 are arranged in inconsistent directions, and the first anti-slip area 31 is arranged obliquely above the second anti-slip area 32.

[0025] When using the above-mentioned easy-to-hold hysteroscopic tissue resection tool, the doctor holds the instrument body 1 and uses the rotary cutting tube 2 to complete minimally invasive surgery on the uterus; with the cooperation of the first anti-slip area 31 and the second anti-slip area 32, different anti-slip effects are achieved for different hand-held positions, and the anti-slip directions are diversified, which greatly improves the doctor's gripping force and ensures the doctor's gripping stability of the instrument body 1, thereby reducing surgical risks and ensuring surgical safety.

[0026] The instrument body 1 includes a tube-mounting portion 12 , which is butted against the gripping portion 11 and integrally formed, and the rotary cutting tube 2 is assembled through the tube-mounting portion 12 .

[0027] The gripping portion 11 has a gripping groove 13 , and the tube-mounting portion 12 has a tube-mounting groove 14 . The gripping groove 13 and the tube-mounting groove 14 are connected and arranged, and the anti-slip member 3 is synchronously embedded in the gripping groove 13 and the tube-mounting groove 14 , thereby realizing the setting of the anti-slip member 3 .

[0028] The tube-mounted groove 14 is arranged in a long strip shape, and the anti-slip part 3 includes a third anti-slip area 33, which is arranged in a long strip shape and embedded in the tube-mounted groove 14; the tube-mounted groove 14 has a tube groove wall, which is arranged in an arched arc shape downward, and the third anti-slip area 33 is arranged flatly and embedded with the tube groove wall, and the third anti-slip area 33 is arranged in an inclined arched arc shape along the direction toward the second anti-slip area 32.

[0029] In this way, the contact area between the finger and the third anti-slip area 33 is increased, thereby ensuring the anti-slip effect of the third anti-slip area 33. The arc-shaped arrangement helps to reduce the pressure on the finger and improve the grip comfort.

[0030] The third anti-slip area 33 is synchronously connected with the first anti-slip area 31 and the second anti-slip area 32 and is arranged in an integral manner, which is convenient for production and assembly of the anti-slip part 3 and the instrument body 1 .

[0031] The third anti-skid area 33 includes a plurality of top anti-skid grooves, each of which is arranged at intervals and correspondingly, and the top anti-skid grooves are arranged to be recessed inwards; under the action of each top anti-skid groove, an anti-skid effect is achieved.

[0032] When holding the grip portion 11, the top anti-skid groove is above the fingers, and when anti-skid is in effect, the top anti-skid groove and the fingers are arranged in vertical contact, ensuring that the anti-skid effect of each top anti-skid groove acts on the fingers, ensuring grip stability.

[0033] The first anti-skid area 31 has a plurality of first anti-skid grooves, each of which is arranged at intervals and correspondingly, and is arranged to be recessed inwards; under the action of each first anti-skid groove, an anti-skid effect is achieved.

[0034] Along the direction away from the tube-mounted portion 12, the first anti-skid grooves are arranged to extend obliquely along the leading direction, so that the extending direction of the first anti-skid grooves is more closely aligned with the force of the hand, thereby improving the anti-skid effect of each first anti-skid groove.

[0035] Along the rearward direction, the lateral spacing of each first anti-skid groove is gradually increased. The larger the spacing, the larger the anti-skid range, ensuring the comprehensive anti-skid effect and helping the cooperation between each first anti-skid groove and the thumb to achieve an anti-skid effect on the thumb area.

[0036] When holding the grip portion 11 , the thumb presses against the first anti-slip area 31 ; the cooperation between each first anti-slip groove and the thumb achieves an anti-slip effect on the thumb.

[0037] The first anti-skid grooves are extended in a direction perpendicular to the thumb. The advantage of such an arrangement is that it helps to enhance the anti-skid effect of each first anti-skid groove on the thumb.

[0038] The second anti-skid area 32 has a plurality of second anti-skid grooves, each of which is arranged at intervals and correspondingly, and is arranged to be recessed inwards; under the action of each second anti-skid groove, an anti-skid effect is achieved.

[0039] The second anti-skid groove is arranged to extend downwardly and obliquely in a direction away from the first anti-skid groove; thus, the second anti-skid groove helps to enhance the anti-skid effect at the palm position.

[0040] Along the direction away from the tube-mounted portion 12, the inclination angles of the second anti-slip grooves are arranged to gradually increase, which is convenient for the doctor to apply the gripping force and at the same time has an anti-slip effect on the ends of each finger.

[0041] When holding the grip portion 11, the palm and the second anti-slip area 32 are arranged in a pressing manner, which helps to enhance the anti-slip effect of the palm position.

[0042] The gripping portion 11 and the anti-slip member 3 are assembled by die-casting; the manufacturing process is simple and the cost is low.

[0043] The die casting method can be a hot pressing method.

[0044] Furthermore, such a manufacturing method helps to enhance the assembly stability between the anti-slip member 3 and the instrument body 1 and prevent the anti-slip member 3 from being accidentally separated.

[0045] The hand-held hysteroscopic tissue removal tool includes two anti-slip parts 3, which are symmetrically arranged, and the two anti-slip parts 3 are arranged to clamp the instrument body 1, and the two anti-slip parts 3 are synchronously assembled with the instrument body 1; in this way, under the action of the two anti-slip parts 3, the anti-slip range is enhanced, so that when the doctor holds it, it has a comprehensive anti-slip effect, thereby ensuring the holding stability of the instrument body 1.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
