Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laser positioning minimally invasive sampling surgical device. Background Art

[0002] With the increasing popularity of ultrasound equipment, more and more clinical medical staff use ultrasound equipment to carry out visualization work. At present, ultrasound guidance of medical technology is mainly concentrated in the field of puncture. The minimally invasive breast surgery of this breast excision system is mainly to perform puncture sampling surgery under ultrasound imaging. In the actual positioning, puncture and sampling process of medical staff, precise alignment and guidance to the sampling site are required, so that sampling and minimally invasive excision surgery can be completed conveniently, quickly and safely.

[0003] At present, ultrasound image-guided puncture technology is to puncture the target site to collect body fluids, tissues, cells or introduce medicine, etc. In our minimally invasive breast surgery, medical staff put the ultrasound probe on the surface of the body to be punctured, and use the puncture needle of the breast excision system to insert the needle along the calculated path to reach the sampling position under the monitoring of the ultrasound probe.

[0004] In the prior art, medical staff place the ultrasonic probe on the surface of the body part to be punctured for positioning, and use the puncture needle of the breast excision system to insert the needle from the side of the breast through the calculated path. Because the puncture needle tip needs to be inserted under the skin and inside the breast tissue, the medical staff cannot directly check the position of the needle tip. They need to move the ultrasonic probe to switch and check the angle and depth of the needle tip, thus losing the reference and direction of the needle tip's advance. Therefore, they can only repeatedly switch the target and needle tip position, and constantly adjust so that the needle tip reaches the target position. During the whole process, the medical staff's glasses need to be constantly switched to observe and confirm, the left hand operates the ultrasonic probe to repeatedly check and confirm the target and needle tip position, and the right hand operates the puncture needle to insert the needle. The patient's needle insertion experience takes a long time, and the affected area is repeatedly squeezed and injured, and the patient suffers additional pain both physically and psychologically. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a laser-positioned minimally invasive sampling surgical device, which can enable the puncture needle to reach the sampling position quickly and accurately, improve the needle insertion efficiency of medical staff, and reduce the pain of patients.

[0006] The utility model is realized by the following technical solutions:

[0007] A laser positioning minimally invasive sampling surgical device comprises an operating handle, a puncture assembly and an ultrasonic probe, wherein the ultrasonic probe is placed at a site to be punctured for positioning, the puncture assembly is fixedly connected to the operating handle for sampling the site to be punctured, a laser generator and a circuit control board electrically connected to the laser generator are arranged in the operating handle, the laser generator is used to emit laser light to visually display the direction of a cutting groove on the puncture assembly, and the laser light emitted by the laser generator can form a laser mark on the ultrasonic probe;

[0008] During the operation, the medical staff holds the ultrasonic probe with one hand to locate the puncture site, and holds the operating handle with the other hand to ensure that the position of the laser mark on the ultrasonic probe remains unchanged so that the puncture assembly moves forward to the sampling position.

[0009] Furthermore, at least one positioning mark is provided on the ultrasonic probe, and during the operation, the relative position between the laser mark and the positioning mark remains unchanged.

[0010] Furthermore, the positioning mark is in the shape of a long strip, and during the operation, the direction of the laser mark remains consistent with that of the positioning mark.

[0011] Furthermore, the puncture assembly includes a puncture needle, and an insertion direction of the puncture needle is perpendicular to an extension direction of the positioning mark.

[0012] Furthermore, a light-transmitting cover is provided on the operating handle, and the laser emitted by the laser generator passes through the light-transmitting cover to the ultrasonic probe.

[0013] Furthermore, a mounting groove is formed at one end of the operating handle close to the light-transmitting cover, and the light-transmitting cover is detachably mounted in the mounting groove.

[0014] Furthermore, an installation cavity is formed between the light-transmitting cover and the operating handle, and the laser generator and the circuit control board are both arranged in the installation cavity.

[0015] Furthermore, a mounting column is protruding from an upper wall forming the mounting cavity, and the circuit control board is fixedly connected to the mounting column.

[0016] Furthermore, the laser generator is fixed below the circuit control board.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. During the process of puncture needle insertion and insertion, after the needle tip of the puncture needle penetrates the tissue, the laser generator on the operating handle is used to align the positioning mark on the ultrasound probe, and the puncture needle is calibrated to the positioning mark. The needle tip penetrates the tissue at the target position depth of the ultrasound probe. During the process of puncturing the tissue, the laser generator can assist the puncture needle to prevent the needle tip from deviating in the insertion direction, so that the needle tip can quickly reach the target position within the ultrasound display range for minimally invasive surgery. The device can enable the puncture needle to reach the sampling position quickly and accurately, improve the efficiency of needle insertion for medical staff, and reduce the pain of patients.

[0019] 2. When the puncture needle is used for minimally invasive surgery, the front of the ultrasound probe is perpendicular to the operating handle, and the laser generator is vertically irradiated onto the large surface of the ultrasound probe. The direction of laser irradiation can intuitively display the direction of the cutting groove on the puncture needle. For breast excision surgery, it can assist medical staff to intuitively and quickly confirm the position of the tissue to be examined and the puncture needle and the direction of the cutting groove.

The laser generator 4 is fixed below the circuit control board 5. The laser generator 4 is used to emit laser light to intuitively display the direction of the cutting groove (not shown) on the puncture assembly 2, and the laser light emitted by the laser generator 4 can form a laser mark 6 on the ultrasonic probe 3. During the operation, the medical staff holds the ultrasonic probe 3 in one hand to locate the site to be punctured, and holds the operating handle 1 in the other hand to ensure that the position of the laser mark 6 on the ultrasonic probe 3 remains unchanged, so that the puncture assembly 2 moves forward to the sampling position.

[0025] At least one positioning mark 30 is provided on the ultrasonic probe 3. During the operation, the relative position between the laser mark 6 and the positioning mark 30 remains unchanged. In this embodiment, four positioning marks 30 are provided on the ultrasonic probe 3 and are arranged circumferentially on the ultrasonic probe 3.

[0026] The positioning mark 30 is in the shape of a long strip. During the operation, the direction of the laser mark 6 is consistent with that of the positioning mark 30, so it is easy to observe whether the laser mark 6 is offset.

[0027] The puncture assembly 2 includes a puncture needle 20 , and an insertion direction X of the puncture needle 20 and an extension direction Y of the positioning mark 30 are perpendicular to each other.

[0028] A light-transmitting cover 7 is provided on the operating handle 1 , and the laser emitted by the laser generator 4 passes through the light-transmitting cover 7 to the ultrasonic probe 3 .

[0032] Beneficial effects of the utility model:

[0033] 1.

The needle tip 200 penetrates the tissue at the target position depth of the ultrasonic probe 3. During the penetration of the tissue, the laser generator 4 can assist the puncture needle 20 to have no deviation in the needle insertion direction, so that the needle tip 200 can quickly reach the target position within the ultrasonic display range, and perform minimally invasive surgery. The device can enable the puncture needle 20 to quickly and accurately reach the sampling position, improve the needle insertion efficiency of medical staff, and reduce the pain of patients.

[0034] 2. When the puncture needle 20 performs minimally invasive surgery, the front of the ultrasonic probe 3 is perpendicular to the operating handle 1, and the laser generator 4 is vertically irradiated onto the large surface of the ultrasonic probe 3. The irradiation direction of the laser can intuitively display the direction of the cutting groove on the puncture needle 20. For breast excision surgery, it can assist medical staff to intuitively and quickly confirm the position of the tissue to be examined and the puncture needle 20 and the direction of the cutting groove.
