Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically referring to a biopsy forceps that can be rotated and clamped. Background Technology

[0002] In recent years, endoscopy has been widely used as an auxiliary diagnostic method. When examining lesions within a patient's body, biopsy forceps can be inserted through the endoscope's forceps channel to grasp and extract diseased tissue. Endoscopic sampling is minimally invasive and causes little pain.

[0003] However, existing biopsy forceps have non-rotatable forceps heads, requiring manual rotation of the handle to position the forceps. During surgery, surgeons need to operate different medical instruments with both hands; if rotation of the forceps head is required, the surgeon must put down the instrument in the other hand to rotate the handle, disrupting the procedure, wasting sample collection time, and reducing the user's medical experience. Therefore, there is an urgent need for a new type of biopsy forceps with a rotating grip to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a rotatable biopsy forceps that uses a drive motor to rotate the protective sleeve of the forceps head, thereby causing the left and right forceps heads to rotate together. This facilitates automatic adjustment of the forceps head direction and improves sampling efficiency.

[0005] The technical solution adopted by this utility model is as follows: This utility model is a rotatable biopsy forceps, including a forceps handle, a forceps head protective sleeve, a left forceps head, a right forceps head, an operating ring, a rotating assembly, and a clamping assembly. The forceps handle is a hollow cavity with one open end. The forceps head protective sleeve is rotatably disposed outside the open end of the forceps handle. An operating tube is fixedly disposed on one side of the forceps head protective sleeve, and the operating tube is rotatably disposed inside the forceps handle. Forceps head sliding grooves are provided on both side walls of the forceps head protective sleeve. The left and right forceps heads are symmetrically hinged inside both ends of the forceps head protective sleeve. The left and right forceps heads both pass through the forceps head sliding grooves. The operating ring is fixedly disposed at the end of the forceps handle away from the forceps head protective sleeve. An annular working groove is provided in the end of the forceps handle away from the forceps head protective sleeve. The rotating assembly is disposed in the annular working groove. The clamping assembly is disposed on one side of the operating tube.

[0006] Furthermore, the rotating assembly includes a rotating gear, a drive motor, and a drive gear. The rotating gear is fixed on the outer side of the operating tube away from the pliers head protective sleeve. The drive motor is fixed in the annular working groove. The drive gear is located at the output end of the drive motor and is rotatably located on one side of the rotating gear. The drive gear meshes with the rotating gear.

[0007] Furthermore, the clamping assembly includes a clamping rod, a connecting block, and a connecting rod. The clamping rod is slidably disposed inside the operating tube, with one end of the clamping rod passing through the operating tube and slidably disposed inside the jaw head protective sleeve. The connecting block is fixed to one end of the clamping rod and slidably disposed between the left and right jaw heads. There are two connecting rods, symmetrically disposed on both sides of the connecting block. One end of the connecting rod is hinged to the connecting block, and the other end of the connecting rod is hinged to the left and right jaw heads.

[0008] Furthermore, an operating arc plate is slidably provided inside the operating ring, and an operating rod is fixedly provided on one side of the operating arc plate. The end of the operating rod away from the operating arc plate passes through the operating ring and the clamp handle and is slidably provided inside the operating tube.

[0009] Furthermore, the end of the operating rod away from the operating arc plate is connected to a sleeve, the inner wall of the connecting sleeve is provided with an annular groove, the end of the connecting rod away from the connecting block is rotatably disposed in the connecting sleeve, and the end of the connecting rod away from the connecting block is fixedly provided with a guide ring, which is rotatably disposed in the annular groove.

[0010] Furthermore, the opening end of the pliers handle is provided with a sealing sleeve, and a sealing ring is fixedly provided on the outside of the operating tube near the protective sleeve of the pliers head, and the sealing ring is rotatably disposed inside the sealing sleeve.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. The drive gear at the output of the drive motor drives the rotating gear to rotate, which in turn drives the operating tube to rotate inside the pliers handle. The operating tube then drives the pliers head protective sleeve to rotate, causing the left and right pliers heads to rotate together. This facilitates automatic adjustment of the pliers head direction and improves sampling efficiency.

[0013] 2. Pull the operating arc plate to move the operating rod and the connecting rod. The connecting block at one end of the connecting rod causes the connecting rod to deform, which in turn causes the connecting rod to pull the left and right clamp heads to rotate, so that the left and right clamp heads can clamp and take samples.

The left head 3 and right head 4 are symmetrically hinged at both ends of the head protection sleeve 2. The left head 3 and right head 4 both pass through the head sliding grooves 9. The operating ring 5 is fixed at the end of the handle 1 away from the head protection sleeve 2. The end of the handle 1 away from the head protection sleeve 2 has an annular working groove 10. The rotating assembly 6 is disposed in the annular working groove 10. The clamping assembly 7 is disposed on one side of the operating tube 8.

[0022] like Figure 2 and Figure 4As shown, the rotating assembly 6 includes a rotating gear 11, a drive motor 12, and a drive gear 13. The rotating gear 11 is fixed on the outer side of the end of the operating tube 8 away from the pliers head protective sleeve 2. The drive motor 12 is fixed in the annular working groove 10. The drive gear 13 is located at the output end of the drive motor 12. The drive gear 13 is rotatably located on one side of the rotating gear 11 and meshes with the rotating gear 11.

[0023] like Figure 2 and Figure 3 As shown, the clamping assembly 7 includes a clamping rod 14, a connecting block 15, and a connecting rod 16. The clamping rod 14 is slidably disposed within the operating tube 8. One end of the clamping rod 14 passes through the operating tube 8 and is slidably disposed within the jaw head protective sleeve 2. The connecting block 15 is fixed to one end of the clamping rod 14 and slidably disposed between the left jaw head 3 and the right jaw head 4. There are two connecting rods 16, which are symmetrically disposed on both sides of the connecting block 15. One end of the connecting rod 16 is hinged to the connecting block 15, and the other end of the connecting rod 16 is hinged to the left jaw head 3 and the right jaw head 4. An operating arc plate 17 is slidably disposed within the operating ring 5. An operating rod 18 is fixedly disposed on one side of the operating arc plate 17.

The operating tube 8 drives the head protective sleeve 2 to rotate, so that the left head 3 and the right head 4 rotate together, which facilitates automatic adjustment of the head direction and improves sampling efficiency.

[0026] When the clamp head protective sleeve 2 rotates, the clamping rod 14 rotates together with the operating tube 8. At this time, one end of the clamping rod 14 rotates inside the connecting sleeve 19, while the operating rod 18 remains stationary, making it convenient to perform sampling operations through the operating rod 18.

[0027] After the angle is adjusted, the doctor holds the end of the operating ring 5 away from the forceps handle 1 and hooks his fingers onto the operating arc plate 17. At this time, sampling begins. The doctor tightens his fingers and moves the operating arc plate 17 away from the forceps handle 1. The operating arc plate 17 pulls the operating rod 18, and the clamping rod 14 connected to the operating rod 18 through the connecting sleeve 19 is pulled. The clamping rod 14 pulls the connecting block 15, causing the connecting rod 16 to deform. The connecting rod 16 pulls the left forceps head 3 and the right forceps head 4 to rotate. At this time, the left forceps head 3 and the right forceps head 4 clamp and sample.
