Description

Technical Field

[0001] This application relates to the field of hemostatic forceps technology, and more specifically, to a uterine hemostatic forceps. Background Technology

[0002] In gynecological surgery, intrauterine hemostatic forceps are commonly used hemostatic tools. Their working principle is similar to clamps, used to grasp blood vessels or skin. Hemostatic forceps come in large and small sizes, toothed and toothless types, and straight and curved shapes; different types of hemostatic forceps are selected according to the different surgical sites.

[0003] The prior art publication (announcement) document CN211934182U provides a uterine hemostatic forceps for obstetric and gynecological clinical use. In this related technology, by setting an adjusting rod, a fastening screw, and a sliding cavity, when using the hemostatic forceps to stop bleeding in patients, the left and right forceps handles slide within the sliding cavity inside the adjusting rod. Then, the fastening screw is rotated to position the left and right forceps handles. This avoids the hemostatic forceps being too short, which would affect the doctor's operation, and increases the applicability of the hemostatic forceps.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following drawbacks: the hemostatic forceps structure has the extension and retraction adjustment function of the forceps handle and the adjusting rod, but cannot adjust the angle of the forceps head, and the effect of use is limited.

[0005] In view of this, we propose a uterine hemostatic forceps. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a uterine hemostatic forceps.

[0007] The intrauterine hemostatic forceps provided in this application adopt the following technical solution:

[0008] A uterine hemostatic forceps includes a telescopically adjustable forceps handle. A semi-ring sleeve is fixedly connected to one end of the forceps handle. A semi-ring handle is slidably connected inside the semi-ring sleeve. A forceps head is fixedly connected to one end of the semi-ring handle, and a fastener is threadedly connected to the other end. The fastener is slidably adapted to the semi-ring sleeve. A connecting ring is fixedly connected inside the semi-ring sleeve, and a positioning pin is rotatably connected between the two connecting rings.

[0009] By adopting the above technical solution, and utilizing the rotational adjustment of the semi-ring sleeve and semi-ring handle, the semi-ring handle for installing the forceps head can be adjusted to multiple angles, meeting the angle usage requirements of the forceps head in different states and improving the versatility of the hemostatic forceps structure.

[0010] As an optional solution to the technical solution of this application, a limiting block is fixedly connected to one side of the clamp handle, wherein one of the limiting blocks is externally hinged with an anti-disengagement hook, and the other limiting block is externally fixedly connected with a collar that can engage with the anti-disengagement hook for limiting.

[0011] By adopting the above technical solution, the connection between the anti-detachment hook and the collar can be used to ensure the stability of the fit between the two limit blocks, achieve a stable closing and storage effect for the pliers handle, and prevent the pliers from opening and causing injury when they fall.

[0012] As an optional solution to the technical solution in this application, the clamp head is composed of a torsion bar and a clamping head that are snapped together.

[0013] By adopting the above technical solution, the pliers head is assembled by snapping together the torsion bar and the clamping head, which makes it easy to replace the clamping head according to the usage environment and ensures the effectiveness of the pliers head.

[0014] As an optional solution to the technical solution of this application, the fastener includes an adjusting screw threaded to one side of the semi-ring shank, a damping block is sleeved on the outside of the adjusting screw, and an arc groove that can fit with the semi-ring shank is opened on one side of the damping block.

[0015] By adopting the above technical solution, the damping block and the semi-ring sleeve can be tightly abutted and limited by the adjusting screw and the threaded connection of the semi-ring sleeve, thereby realizing the connection and fixation between the semi-ring sleeve and the semi-ring sleeve, and achieving the function of changing the angle of the pliers head.

[0016] As an optional solution to the technical solution of this application, a limiting groove is provided at one end of the adjusting screw, a torsion bar is slidably connected in the limiting groove, and a damping sleeve is sleeved on the outside of the torsion bar.

[0017] By adopting the above technical solution, a torsion bar is slidably connected inside the adjusting screw, so that the torsion bar can form a lever arm when it is stretched to limit the adjustment screw, thereby adjusting the adjusting screw to make it convenient to use for rotation adjustment.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application utilizes the rotational adjustment of the semi-ring sleeve and the semi-ring handle to achieve multi-angle offset adjustment of the semi-ring handle on which the forceps head is installed, thereby meeting the angle usage requirements of the forceps head in different states and improving the versatility of the hemostatic forceps structure.

[0020] 2. This application utilizes a torsion bar that slides inside the adjusting screw, so that the torsion bar can form a lever arm when it is stretched to the limit, thereby adjusting the adjusting screw by torsion and making the adjustment screw rotation adjustment convenient.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1-3 The intrauterine hemostatic forceps described in this application include a telescopically adjustable forceps handle 1. One end of the forceps handle 1 is fixedly connected to a semi-ring sleeve 2. A semi-ring handle 3 is slidably connected inside the semi-ring sleeve 2. One end of the semi-ring handle 3 is fixedly connected to a forceps head 4, and the other end is threadedly connected to a fastener 5. The fastener 5 is slidably adapted to the semi-ring sleeve 2, and a connecting ring 6 is fixedly connected inside the semi-ring sleeve 2. A positioning pin 7 is rotatably connected between the two connecting rings 6.

[0027] This intrauterine hemostatic forceps, by utilizing the rotational adjustment of the semi-ring sleeve 2 and the semi-ring handle 3, allows for multi-angle offset adjustment of the semi-ring handle 3 on which the forceps head 4 is installed, meeting the angle usage requirements of the forceps head 4 in different states and improving the versatility of the hemostatic forceps structure.

[0028] Reference Figure 2 and Figure 1 In the embodiment of this application, the uterine hemostatic forceps has a limiting block 11 fixedly connected to one side of the forceps handle 1. One limiting block 11 is externally hinged with an anti-disengagement hook 12, and the other limiting block 11 is externally fixedly connected with a collar 13 that can be hooked and limited with the anti-disengagement hook 12.

[0029] This uterine hemostatic forceps, by utilizing the hook-and-loop connection between the anti-dislodgement hook 12 and the collar 13, can ensure the stable fit between the two limiting blocks 11, achieve a stable closed storage effect for the forceps handle 1, and prevent the forceps from falling and unfolding, thus preventing injury.

[0030] Reference Figure 2 and Figure 1The forceps head 4 in the uterine hemostatic forceps described in this application embodiment is composed of two parts: a torsion bar 41 and a snap-fit ​​clamp 42, which are snapped together and installed.

[0031] This intrauterine hemostatic forceps consists of a forceps head 4, which is assembled by two parts: a torsion bar 41 and a clamping head 42. This allows the forceps body to be easily replaced with the clamping head 42 according to the usage environment, ensuring the effectiveness of the forceps head 4.

[0032] Reference Figure 3 and Figure 1 The fastener 5 in the intrauterine hemostatic forceps described in this application embodiment includes an adjusting screw 51 threadedly connected to one side of the semi-ring handle 3. A damping block 52 is sleeved on the outside of the adjusting screw 51. An arc-shaped groove that can fit with the semi-ring handle 3 is opened on one side of the damping block 52. A limiting groove is opened at one end of the adjusting screw 51. A torsion rod 53 is slidably connected in the limiting groove. A damping sleeve is sleeved on the outside of the torsion rod 53.

[0033] This uterine hemostatic forceps utilizes an adjusting screw 51 threadedly connected to a semi-ring handle 3. This allows the damping block 52 to be pushed to a tight contact with the semi-ring sleeve 2, thus achieving a fixed connection between the semi-ring handle 3 and the semi-ring sleeve 2. This enables the forceps head 4 to be used at different angles. The adjusting screw 51 is internally connected to a torsion bar 53, which forms a lever arm when the torsion bar 53 is stretched to limit its position. This allows for torsional adjustment of the adjusting screw 51, making it convenient to use for rotational adjustment.

[0034] Working principle: When it is necessary to adjust the clamping angle of the pliers head 4, the operator pulls the torsion bar 53, which slides and retracts inside the adjusting screw 51, to extend it outward, so that the torsion bar 53 and the adjusting screw 51 are perpendicular to each other.

[0035] Next, rotating the torsion bar 53 counterclockwise causes the adjusting screw 51 and the half-ring handle 3 to release spirally. At this time, the damping block 52 disengages from the tight pressing limit on the half-ring sleeve 2, enabling flexible rotation between the half-ring handle 3 and the half-ring sleeve 2.

[0036] Finally, after adjusting the rotational position between the semi-ring handle 3 and the semi-ring sleeve 2, tighten the fastener 5 to limit the position.
