[0001] The utility model relates to the technical field of medical devices, in particular to a quick disassembly and assembly structure for a puncture target and a prostate biopsy device. Background Technique

[0002] The prostate is an accessory gland of the male reproductive system. It is an unpaired parenchymal gland located between the bladder and the urogenital diaphragm, surrounding the root of the urethra. Its shape and size are similar to those of a slightly flattened chestnut. The upper end is wide, the lower end is pointed, and the back of the body is relatively flat, close to the rectum, and can be touched by digital rectal examination. The longitudinal diameter is 3 cm, the transverse diameter is 4 cm, the anteroposterior diameter is 2 cm, and the weight is about 20 g. Its size and function largely depend on androgens. The prostate of children is very small and grows rapidly during sexual maturity; the glandular tissue of the elderly gradually degenerates, and connective tissue proliferation in the gland forms prostate hyperplasia, compressing the urethra and causing difficulty in urination.

[0003] The treatment methods for the prostate include drugs, physical therapy, and surgery. Among them, prostate puncture biopsy is the most common technique for detecting prostate cancer. During the operation, a puncture guide needs to be set on the surgical device to puncture and sample abnormal areas of the prostate.

[0029] Embodiment

[0030] Please refer to Figures 1 to 4 As shown, this embodiment provides a quick disassembly and assembly structure for a puncture target, which includes a mounting base 1, a first clamping member 2, a second clamping member 3 and a guide 4, wherein:

[0031] A puncture target is slidably mounted at the first end of the mounting base 1. A clamping portion 10 is provided at the second end of the mounting base 1. The first clamping member 2 is rotatably hinged to the first side of the clamping portion 10 through a first elastic torsion shaft 5. The first elastic torsion shaft 5 is configured to provide the clamping force of the first clamping member 2. The second clamping member 3 is rotatably hinged to the second side of the clamping portion 10 through a second elastic torsion shaft 6. The second elastic torsion shaft 6 is configured to provide the clamping force of the second clamping member 3. The first side and the second side are opposite to each other.

[0032] The clamping portion 10, the first clamping member 2 and the second clamping member 3 form a clamping cavity 7. The guide 4 is disposed through the clamping cavity 7 and is clamped and fixed in the clamping cavity 7 by the first clamping member 2 and the second clamping member 3 to mount the mounting base 1 on the guide 4.

[0033] It can be seen that the mounting base 1 is fixed on the guide 4 by the pre-tightening elastic force generated by the first clamping member 2 and the second clamping member 3. The structure is simple, convenient for disassembly and assembly, and improves the disassembly and assembly efficiency.

[0034] As an implementation manner, a connection component 8 is further provided between the first clamping member 2 and the second clamping member 3. When removing the mounting seat 1 from the guide 4, the first clamping member 2 rotates away from the clamping portion 10 and drives the second clamping member 3 to rotate away from the clamping portion 10 through the connection component 8, so as to loosen the mounting seat 1 relative to the guide 4.

[0035] It can be seen that by providing the connection component 8, the linkage between the first clamping member 2 and the second clamping member 3 is realized, which further facilitates the disassembly and assembly of the mounting seat 1, and is also beneficial to improving the clamping stability and reliability of the first clamping member 2 and the second clamping member 3.

[0036] As an implementation manner, the clamping portion 10 includes a first connection portion 100 and a second connection portion 101. The first connection portion 100 is provided on the first side of the mounting seat 1, the first elastic torsion shaft 5 is provided on the first connection portion 100, the second connection portion 101 is provided on the second side of the mounting seat 1, the second elastic torsion shaft 6 is provided on the second connection portion 101, and the first connection portion 100 and the second connection portion 101 are arranged at intervals.

[0037] Preferably, the distance between the first connection portion 100 and the mounting seat 1 is greater than the distance between the second connection portion 101 and the mounting seat 1.

[0038] It can be seen that setting the height difference between the first connection portion 100 and the second connection portion 101 facilitates the installation of the guide 4 and improves the installation efficiency.

[0039] As an implementation manner, the first end of the first clamping member 2 is rotatably connected to the first connection portion 100. A receiving hole 20 is formed in the first clamping member 2. A third elastic torsion shaft 21 is provided in the receiving hole 20. The first end of the connection component 8 is rotatably connected to the third elastic torsion shaft 21. A handle member 22 is provided at the second end of the first clamping member 2, and the handle member 22 is configured to facilitate the manual rotation of the first clamping member 2.

[0040] Specifically, the connection component 8 includes a T-shaped connecting member, and the T-shaped connecting member is rotatably arranged in the receiving hole 20.

[0041] It can be seen that by rotatably arranging the connection component 8 in the receiving hole 20, the occupied space for clamping the guide 4 is reduced.

[0042] Specifically, the handle member 22 is obliquely arranged at the second end of the first clamping member 2.

[0043] It can be seen that by obliquely arranging the handle member 22, it is convenient to arrange the connection component 8 in the receiving hole 20 and to adjust the rotation angle of the first clamping member 2, which has the advantage of being easy to operate.

[0044] As an implementation manner, the first end of the second clamping member 3 is rotatably connected to the second connecting portion 101. The second end of the second clamping member 3 is provided with a third connecting portion 30 and a connecting rod 31. The second end of the connecting assembly 8 is rotatably connected to the third connecting portion 30 through the connecting rod 31.

[0045] Specifically, a curved surface is provided on the second clamping member 3, and the curved surface is configured to fit the connecting portion of the introducer 4.

[0046] It can be seen that by providing the second clamping member 3, the connection stability of the introducer 4 is improved.

[0047] As an implementation manner, a sliding groove 11 is provided at the first end of the mounting base 1, and the piercing target is slidably mounted in the sliding groove 11.

[0048] Specifically, the piercing target rotates through a fastener 12 provided on the side of the sliding groove 11 to adjust the tightness between the piercing target and the sliding groove 11.

[0049] It can be seen that by providing the sliding groove 11 and the fastener 12, the structure is simple and convenient for adjustment.

[0050] As an implementation manner, at least one support limiting block 13 is provided on the mounting base 1. One end of the support limiting block 13 is clamped on the introducer 4, and the support limiting block 13 is configured to limit the mounting position of the mounting base 1 so that the mounting base 1 can be quickly mounted on the introducer 4.

[0051] Preferably, one support limiting block 13 is provided at each end of the mounting base 1 along the length direction of the clamping cavity 7.

[0052] It can be seen that by providing the support limiting block 13, the disassembly and assembly speed and installation accuracy of the mounting base 1 are improved, and further the disassembly and assembly efficiency of the piercing target is improved.

[0053] A prostate biopsy device includes the above-mentioned quick disassembly and assembly structure of the piercing target.

[0054] The specific working principle of the above-mentioned quick disassembly and assembly structure of the piercing target is as follows:

[0055] Insert the introducer 4 into the clamping cavity 7 on the mounting base 1, fix it by the support limiting block 13, abut the second clamping member 3 against the introducer 4, rotate the first clamping member 2 to retract the connecting assembly 8 into the accommodating hole 20, and press the handle member 22 to drive the inner surface of the first clamping member 2 to abut against the outer surface of the second clamping member 3 to complete the fixation of the introducer 4; rotate the first clamping member 2 through the handle member 22 so that the inner surface of the first clamping member 2 is away from the outer surface of the second clamping member 3. At this time, the second end of the connecting assembly 8 is located outside the accommodating hole 20, and the introducer 4 is taken out to complete the disassembly.

[0056] In the embodiments disclosed by the present utility model, terms such as "installation", "connection", "attachment", "fixation", etc. shall be understood in a broad sense. For example, "connection" may be a fixed connection, a detachable connection, or an integral connection; "attachment" may be a direct attachment or an indirect attachment through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments disclosed by the present utility model may be understood according to specific circumstances.

[0057] The above embodiments only illustrate the basic principles and characteristics of the present utility model. The present utility model is not limited by the above examples. Without departing from the spirit and scope of the present utility model, there are various changes and modifications to the present utility model, and these changes and modifications all fall within the scope of the present utility model claimed.
