Description

Technical Field

[0001] The utility model belongs to the field of medical surgical instruments, in particular to a surgical separation forceps with an ultrasonic probe. Background Art

[0002] Transaxillary non-pneumatic laparoscopic thyroidectomy is a relatively recent laparoscopic thyroid surgery procedure. Currently, this procedure is gaining increasing acceptance among physicians and patients. However, it also has certain disadvantages. For example, it is impossible to visually assess the gap between the sternal head and the sternocleidomastoid muscle. This gap must be gradually exposed through the surgeon's experience and the use of instruments such as separating forceps or ultrasonic scalpels, increasing the difficulty and duration of the procedure.

[0003] In the prior art, an ultrasound probe is typically placed on the surface of the sternocleidomastoid muscle. The ultrasound image transmitted by the ultrasound probe is used to determine the gap between the clavicular head and the sternal head of the sternocleidomastoid muscle. This gap is then exposed using an ultrasonic scalpel or separation forceps for blunt dissection, facilitating further surgical procedures. However, the existing ultrasound probes and separation forceps used in laparoscopic surgery are separate instruments. During the procedure, these two instruments (ultrasound probe and separation forceps) must be repeatedly exchanged within the narrow space between the axillary incision and the cervical tunnel. This is extremely cumbersome and inconvenient, significantly increasing surgical time and requiring improvement. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a surgical separation forceps with an ultrasonic probe.

[0005] The utility model adopts the following technical solutions:

[0006] A surgical separation forceps with an ultrasonic probe comprises a separation forceps head, an extension rod, a handle, an ultrasonic detection mechanism and a steering mechanism, wherein the separation forceps head, the extension rod and the handle are connected end to end in sequence, and the handle controls the separation forceps head to open and close to separate tissue; the ultrasonic detection mechanism comprises a probe, an imager and a wire, and the probe is arranged in the separation forceps head; the wire is arranged in the extension rod, one end of which is connected to the probe, and the other end extends into the handle and extends from the handle to be connected to an external imager; the steering mechanism comprises a rotating part, a traction rope and a rotating rod, the rotating part is rotatably arranged at the end of the extension rod, and the separation forceps head is arranged on the rotating part and rotates therewith; two traction ropes are provided, which are respectively located on both sides of the rotating axis of the rotating part and connected to both sides of the rotating part; the rotating rod is rotatably arranged in the extension rod, and the upper and lower sides are respectively connected to the two traction ropes, and the rotating rod rotates to drive the traction rope on one side to extend and the traction rope on the other side to shorten to drive the rotating part to rotate.

[0007] Preferably, it also includes a driving mechanism, which is arranged between the separation pliers head and the handle to drive the separation pliers head to open and close, including a slide groove, a sliding block, a connecting rod assembly, a limit block, a spring and a driving rope, and the slide groove is formed in the rotating part; the sliding block can be moved axially and is arranged in the sliding groove; the connecting rod assembly is connected between the top of the sliding block and the separation pliers head, and the separation pliers head is driven to open or close by moving the sliding block; the limit block is arranged in the slide groove to limit the moving range of the sliding block; the spring is connected between the bottom of the sliding block and the limit block to drive the sliding block to reset; one end of the driving rope is connected to the bottom of the sliding block, and the other end extends to the extension rod and is connected to the handle, and the handle drives the driving rope to extend or shorten to drive the sliding block to move.

[0008] Preferably, the separation pliers head includes an upper pliers mouth and a lower pliers mouth, and the upper pliers mouth and the lower pliers mouth are respectively rotatably arranged in the rotating part. The connecting rod assembly includes a first connecting rod and a second connecting rod, and one end of the first connecting rod and the second connecting rod are respectively connected to the upper pliers mouth and the lower pliers mouth, and the other end is coaxially connected to the sliding block.

[0009] Preferably, the handle includes a fixed handle rod and a rotating handle rod, and the fixed handle rod is connected to the extension rod; the rotating handle rod can be rotatably set on the fixed handle rod, and has a rotating groove formed around the rotating axis inside, one end of the driving rope is connected to the limit block, and the other end is fixed to the bottom of the rotating groove and fits on the inner wall of the rotating groove. As the rotating handle rod rotates counterclockwise, the length of the driving rope in the extension rod can be increased, so that the spring drives the sliding block to move forward to open the separation pliers head, or it can be rotated clockwise to shorten the length of the driving rope in the extension rod to drive the sliding block to move backward to close the separation pliers head.

[0010] Preferably, the handle is further provided with a fixing rod and a fixing hook, the fixing rod is provided on the rotating handle rod; the fixing hook is rotatably provided on the fixing handle rod and can be rotatably matched with the fixing rod to fix the state of the handle.

[0011] Preferably, the extension rod is rotatably arranged on the fixed handle rod around its axis, and also includes a limiting mechanism arranged between the two to limit the rotation range of the two.

The limiting groove is annular and is not connected at both ends; the limiting rod is arranged on the fixed handle rod opposite to the limiting groove and extends into the limiting groove.

[0012] Preferably, a valve is provided on the outside of the rotating rod to facilitate the rotation of the rotating rod.

[0013] Preferably, a sealing leather sleeve is provided between the rotating part and the extension rod.

At the same time, the separation forceps head and the probe can be steered to a certain extent by the steering mechanism, thereby further improving the operability of the device.

[0015] The sliding block is connected by a driving rope, and the driving rope is controlled to extend or shorten to control the opening or closing of the separation clamp head. At the same time, this structure is less likely to affect the steering of the separation clamp head;

[0016] When the separation forceps head is in the closed state, the spring is compressed between the sliding block and the limit block, causing the sliding block to move forward to open the separation forceps head. Therefore, the fixing hook cooperates with the fixing rod to fix the limit handle position to keep the separation forceps head in the closed state. The surgical operator does not need to hold the handle tightly for a long time to keep the separation forceps head closed, which is more labor-saving.

[0017] The extension rod is rotatably mounted on the handle, allowing the separating forceps head to rotate within a certain range to better separate tissues. This allows the operator to simply rotate the extension rod without having to rotate the handle, resulting in easier operation. Furthermore, a limit mechanism limits the extension rod's rotation range to prevent excessive rotation that could damage the wires inside the extension rod.

[0018] The sealing leather sleeve is used to seal the connection between the extension rod and the rotating part to prevent tissue fluid in the patient's body from flowing into the gap between the two when the extension rod is extended into the patient's body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention is further described below through specific implementation methods.

[0029] Figures 1 to 8 As shown, a surgical separation forceps with an ultrasonic probe 41 includes a separation forceps head 1, an extension rod 2, a handle 3, an ultrasonic detection mechanism 4, a steering mechanism 5, a driving mechanism 6, and a limiting mechanism 7.

[0030] The separation forceps head 1, the extension rod 2 and the handle 3 are connected end to end in sequence, and the handle 3 controls the separation forceps head 1 to open and close to separate the tissue. The separation forceps head 1 includes an upper jaw 11 and a lower jaw 12 that can rotate relative to each other for separating tissue. The extension rod 2 is a hollow tube body, and the interior can be used for wire to pass through. The extension rod 2 is rotatably arranged on the handle 3 around its axis, which can make the separation forceps head 1 rotate to a certain extent to better separate the tissue, so that the operator only needs to rotate the extension rod 2 without rotating the handle 3, which is better for operation. The handle 3 includes a fixed handle rod 31 and a rotating handle rod 32. The fixed handle rod 31 is connected to the extension rod 2; the rotating handle rod 32 can be rotatably arranged on the fixed handle rod 31 to drive the separation forceps head 1 to open and close. Specifically, the extension rod 2 and the handle 3 are damped and connected. After rotation, there is resistance between the two to prevent the extension rod 2 from resetting.

[0031] The ultrasonic detection mechanism 4 includes a probe 41, an imager 42, and a wire 43. The probe 41 is mounted on the separating forceps 1. The wire 43 is mounted in the extension rod 2, one end of which is connected to the probe 41, and the other end of which extends into the handle 3 and extends from the handle 3 to connect to the external imager 42. By mounting the probe 41 on the separating forceps 1, the ultrasonic detection mechanism 4 can provide real-time feedback imaging while also performing tissue separation to achieve the desired surgical position, thereby reducing the time required to replace surgical instruments and improving surgical efficiency.

[0032] The steering mechanism 5 includes a rotating portion 51, a traction rope 52, a rotating rod 53, and a valve 54. The rotating portion 51 is rotatably mounted at the end of the extension rod 2, and the separating forceps head 1 is mounted on the rotating portion 51 and rotates with it. Two traction ropes 52 are provided, one on each side of the rotating portion 51's rotation axis and connected to each side of the rotating portion 51. The rotating rod 53 is rotatably mounted within the extension rod 2, with the upper and lower sides connected to the two traction ropes 52, respectively. Rotating the rotating rod 53 causes one traction rope 52 to extend and the other to shorten, thereby rotating the rotating portion 51. The valve 54 is located on the outer side of the rotating rod 53 to facilitate the operator's operation of rotating the rotating rod 53 to rotate the rotating portion 51. The steering mechanism 5 allows the separating forceps head 1 and the probe 41 to steer to a certain degree, further improving the operability of the device. Specifically, a sealing sheath 68 is provided between the rotating portion 51 and the extension rod 2. The sealing sheath 68 is used to seal the connection between the extension rod 2 and the rotating portion 51 to prevent tissue fluid from flowing into the device through the gap between the two when the extension rod 2 is inserted into the patient's body.

[0033] The driving mechanism 6 is arranged between the separation pliers head 1 and the handle 3 to drive the separation pliers head 1 to open and close, and includes a slide groove 61, a sliding block 62, a connecting rod assembly 63, a limit block 64, a spring 65 and a driving rope 66. The slide groove 61 is formed in the rotating part 51; the sliding block 62 can be moved axially in the slide groove; the connecting rod assembly 63 is connected between the top of the sliding block 62 and the separation pliers head 1, and the separation pliers head 1 is driven to open or close by moving the sliding block 62; the limit block 64 is arranged in the slide groove 61 to limit the moving range of the sliding block 62; the spring 65 is connected between the bottom of the sliding block 62 and the limit block 64 to drive the sliding block 62 to reset; one end of the driving rope 66 is connected to the bottom of the sliding block 62, and the other end extends to the extension rod 2 and is connected to the handle 3. The handle 3 drives the driving rope 66 to extend or shorten to drive the sliding block 62 to move. The handle 3 also includes a fixing rod 33 and a fixing hook 34. The fixing rod 33 is disposed on the rotating handle rod 32; the fixing hook 34 is rotatably disposed on the fixed handle rod 31 and can be rotated to cooperate with the fixing rod 33 to fix the state of the handle 3. When the separating forceps head 1 is in the closed state, the spring 65 is compressed between the sliding block 62 and the limit block 64, causing the sliding block 62 to move forward to open the separating forceps head 1. Therefore, the fixing hook 34 cooperates with the fixing rod 33 to fix and limit the position of the handle 3 so that the separating forceps head 1 is in the closed state. The surgical operator does not need to hold the handle 3 tightly for a long time to keep the separating forceps head 1 closed, which is more labor-saving.

[0034] Specifically, the upper jaw 11 and the lower jaw 12 are respectively rotatably arranged in the rotating part 51, and the connecting rod assembly 63 includes a first connecting rod and a second connecting rod. One end of the first connecting rod and the second connecting rod are respectively connected to the upper jaw 11 and the lower jaw 12, and the other end is coaxially connected to the sliding block 62.

[0035] Furthermore, there is a rotating groove 67 formed around the rotating axis inside the rotating handle rod 32, one end of the driving rope 66 is connected to the limit block 64, and the other end is fixed to the bottom of the rotating groove 67 and fits on the inner wall of the rotating groove 67. As the rotating handle rod 32 rotates counterclockwise, the length of the driving rope 66 in the extension rod 2 increases, so that the spring 65 drives the sliding block 62 to move forward to open the separating pliers head 1, or rotates clockwise to shorten the length of the driving rope 66 in the extension rod 2 to drive the sliding block 62 to move backward to close the separating pliers head 1. The sliding block 62 is connected by the driving rope 66, and the driving rope 66 is controlled to extend or shorten to control the opening or closing of the separating pliers head 1, so that the separation pliers head 1 can be opened and closed at the same time. This structure is less likely to affect the steering of the separating pliers head 1.

[0036] The limiting mechanism 7 is arranged between the extension rod 2 and the fixed handle rod 31 to limit the rotation range of the two, including a limiting groove 71 and a limiting rod 72. The limiting groove 71 is arranged on the contact surface of the extension rod 2 and the fixed handle rod 31 around the rotation axis of the extension rod 2. The limiting groove 71 is annular and the two ends are not connected; the limiting rod 72 is arranged on the fixed handle rod 31 opposite to the limiting groove 71 and extends into the limiting groove 71. The limiting mechanism 7 limits the rotation range of the extension rod 2 to prevent it from excessive rotation and causing damage to the wires inside the extension rod 2.

[0037] During use, the operator controls the rotating handle 32 to rotate in the direction close to the fixed handle 31, and coordinates the state of the fixed handle 3 with the fixed hook 34 and the fixed rod 33 to put the separation forceps 1 in a closed state. Then the ultrasonic detection mechanism 4 is turned on, and the operator controls the separation forceps 1 to extend into the patient's body, and observes the real-time feedback signal from the probe 41 from the imager 42, gradually approaching the lesion along the gap between the clavicle head and the sternal head. When it is necessary to separate the tissue, the fixed hook 34 is separated from the fixed rod 33, and the operator controls the opening and closing of the separation forceps 1 by loosening the handle 3 to separate the tissue, so that the instrument can continue to move forward. During the forward movement, the extension rod 2 can also be rotated and the steering rod can be operated to rotate to control the rotation and steering of the separation forceps 1, so that it can move forward better and perform tissue separation, making it easier for the instrument to reach the required surgical position, reducing the time for changing surgical instruments and improving surgical efficiency.

[0038] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the present patent.
