Description

Technical Field

[0001] The present invention relates to the field of medical health, and specifically to a device for removing abdominal tumors. The device is used to remove and remove abdominal masses such as the stomach, intestines, and abdomen without opening the abdominal cavity, and does not affect pathological analysis. The device is used to minimally segment surgically removed stomach, intestines, and abdominal masses so that they can be removed through existing surgical puncture holes in the abdominal cavity and the tissue morphology can be restored in vitro to facilitate pathological examination. Background Art

[0002] Currently, laparoscopic and robotic minimally invasive surgeries can be performed by making 3-5 small incisions (usually 0.2-

[0003] A small 1.5 cm puncture hole is used to remove gastrointestinal tumors or retroperitoneal masses, such as Figure 1 As shown (the puncture holes are for illustration only, and the actual surgery may be different from the examples), after the gastrointestinal tumor or abdominal mass is removed, the tumor, mass and its attached tissues that have been removed are as follows: Figure 2 As shown in Figure 2, it is impossible to remove the resected tumor directly from the laparoscopic port. The most common method to remove the resected tumor is to make a new 4-6 cm incision in the abdomen to remove the resected tumor and its attached tissues. Figure 3 The puncture holes and incisions shown are for illustrative purposes only and may differ from those in the actual surgery. Alternatively, the resected material may be removed by opening the normal intestines, vagina, or other organs. The removed material is then treated with formalin and sent to the pathology department for pathological examination.

[0004] Existing laparoscopic minimally invasive surgeries are performed manually by the surgeon, while robotic minimally invasive surgery consists of three components: a surgeon's console, a bedside robotic arm system, and a video imaging system. The surgeon sits at the console, observing the surgical field through a stereoscopic eyepiece. The surgeon performs the surgery using a controller that remotely controls the bedside robotic arm and camera. The controller precisely synchronizes the surgical instruments with the surgeon's hands. The surgical robot's video imaging system can magnify the surgical area and create a three-dimensional image, providing a clearer and more realistic surgical field of view, more precise surgery, and enabling the surgeon to perform more complex operations. Compared to laparoscopic minimally invasive surgery, robotic minimally invasive surgery is more precise, less invasive, and less prone to bleeding, while also accelerating the patient's recovery.

[0005] In actual surgery, the pathology department needs to maintain the integrity of the removed tumor and its accompanying tissues as much as possible when performing pathological analysis on the removed material (gastrointestinal tumors, abdominal retroperitoneal tumors). Therefore, it cannot be crushed and removed within the abdominal cavity. Currently, hysteroscopic resection of uterine fibroids is performed by using a knife to remove the tumor in pieces or fragments within the uterine cavity and then send it for pathological examination. For other malignant tumors, it is hoped that the integrity of the tumor and its accompanying tissues will be maintained as much as possible.

[0006] While it's possible to completely remove the tumor and its appendages by making another abdominal incision or opening the normal intestine or vagina, both methods involve additional incisions and trauma, potentially leading to infection or even non-healing. A minimally invasive surgery would be considered ideal if no additional abdominal or intestinal / vaginal incisions were made to remove the resected material. However, because the tumor may be large and the tissue is relatively hard, it cannot be removed through the abdominal puncture hole used for surgery.

[0007] However, in order to minimize trauma to the patient, it would be a better surgical option if it can be removed relatively completely without performing an open surgery. Summary of the Invention

[0008] In order to overcome the shortcomings of the existing technology, the present invention provides a gastrointestinal and abdominal tumor cutting and removal device solution for laparoscopic and robotic minimally invasive surgery, so as to achieve the purpose of more complete removal of the resected tumor and its appendages without performing open surgery and with less trauma to the patient. The removed tumor and its appendages can also be simply sutured together outside the body after the operation, without affecting routine pathological examination.

[0009] The solution adopted by the present invention to solve the technical problem is:

[0010] Provided is an abdominal tumor removal and retrieval device, comprising an external handheld portion, a connecting portion, and an internal removal portion, wherein the external handheld portion comprises an operating handle; the connecting portion comprises an operating rod; the internal portion comprises a sleeve, a clamp, and a shear, wherein the sleeve is a multi-lobe cylindrical structure, comprising a sleeve base and a multi-lobe elongated cylinder, and the clamp and the shear are located inside the multi-lobe elongated cylinder;

[0011] The operating rod includes a control connector, which is matched and connected with the shear and the clamp respectively;

[0012] The clamp includes a front clamping part and a rear clamping part connecting piece; the shears include a front cutting part and a rear cutting part connecting piece; the clamping part connecting piece and the cutting part connecting piece are respectively connected to the operating handle through the operating rod for control.

[0013] The operating handle includes several operating elements, including buttons, pull rods or pressure handle structures.

[0014] The operating stem includes a control connector and an external sleeve. The external sleeve is made of a hard material, such as high-hardness polyurethane.

[0015] The multi-petal structure long cylinder of the sleeve is an expandable multi-petal structure, which becomes a cylinder after closing. The opening and closing of the multi-petal cylinder mechanism is realized by a connecting rod mechanism.

[0016] The present invention solves the technical problem by employing a solution: During surgery for gastrointestinal and abdominal-pelvic tumors, the tumor and a portion of adjacent tissue must be removed within the abdominal cavity. If the resected tumor and its adjacent tissue cannot be directly removed through the laparoscopic port, the tumor and its adjacent tissue must be cut and divided within the abdominal cavity into removable sizes (e.g., tumors exceeding 4 cm in diameter).

[0017] To prevent the tumor from fragmenting and contaminating the abdominal cavity during intraperitoneal excision, the resected tissue must first be placed in a disposable specimen isolation bag. This double-sided bag is opened and inserted into the abdominal cavity through the laparoscopic puncture port. The bag is then placed over the tumor and its accompanying tissues. A surgical plastic clip is then inserted into the abdominal cavity, with one opening clamped closed. The other opening remains outside the abdominal cavity. Once the internal portion of the bag is sealed, the bag is opened and the sleeve is inserted deeper into the bag, with the clamps and shears inside the sleeve not extended.

[0018] Extend the clamp from the inside of the sleeve and clamp one end of the surgical specimen to be cut off. If the surgical specimen is too large to enter the sleeve, the multi-link structure sleeve on the sleeve can be opened to a size that the surgical specimen can enter by operating the handle. At this time, use the clamp to continuously pull the surgical specimen to be removed into the sleeve and cut it with the scissors until the surgical specimen to be removed is divided into two parts. If it still cannot be removed from the laparoscopic puncture hole at this time, the above operation can be repeated until the surgical specimen to be removed is divided into several parts that can be removed through the laparoscopic puncture hole.

[0019] Beneficial effects

[0020] The present invention relates to a novel device for cutting and removing surgical specimens for gastrointestinal tumors and abdominal and pelvic tumors. Its primary purpose is to address the problem of being unable to remove the surgical specimen through the minimally invasive laparoscopic puncture port after minimally invasive abdominal surgery, requiring a separate laparotomy. Furthermore, if the surgical specimen is removed solely through minimally invasive laparoscopic surgery, the colon must be fragmented in vivo, making pathological analysis impossible after removal and easily contaminating the abdominal cavity with blood and tissue fragments from the fragmentation.

[0021] The solution is to use a sleeve to cover the surgical specimen to be removed and use internal clamps and scissors to cut it, dividing the hard and large tissue that cannot be removed into several tissues with a diameter smaller than the minimally invasive laparoscopic puncture hole, and then removing them one by one through the minimally invasive laparoscopic puncture hole. All of the above steps are carried out within the isolation bag, and the resulting blood and tissue fragments will not contaminate the abdominal cavity. The surgical specimen removed by the scissors is a uniform and smooth strip structure, which can be completely spliced together in vitro with simple suturing for pathological analysis.

[0022] The novel surgical specimen cutting and removal device of the present invention will make existing laparoscopic surgery and robotic surgery truly minimally invasive without making incisions. New incisions will no longer be required to remove specimens, which can shorten the patient's postoperative recovery time, reduce the possibility of intraoperative contamination, reduce the possibility of postoperative incision infection, and relieve the patient's anxiety about surgery.

DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Based on the description in the present invention, all other technical solutions obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] according to Figure 4-9 The main structures of the invention are arranged in a line, from the outside to the inside of the body, respectively, the operating handle 2, the operating rod 3, the sleeve 4, the clamp 5, and the scissors 6. These structures are all enclosed in a disposable specimen isolation bag and have no contact with the healthy part of the human body.

[0037] The operating handle 2 is mainly used to manually control other structures and operate the part of the patient's body that needs to be cut. It includes buttons, hooks, levers, grips and other structures. Figure 4 .

[0038] The operating handle 2 is connected to the operating rod 3. The operating rod 3 includes an external sleeve 31 and an internal control connector 32. The external sleeve 31 is made of hard material at the position connected to the operating handle 2, and the other parts are made of flexible material to better bend inside and outside the body. Figure 5 .

[0039] In one embodiment, the control connection member 32 includes a connecting wire or a connecting rod.

[0040] In one embodiment, the two operating handles have different buttons 21, multiple pull rods 22, and multiple pressure handles 23 to control different movements of the internal parts. The buttons 21 control the opening and closing of the shears 6; the multiple pull rods 22 control the extension and retraction of the clamps 5; and the multiple pressure handles 23 control the tightening and loosening of the clamps 5. Figure 6 .

[0041] The outer sleeve 31 is a hollow structure, housing an internal control connector 32. This connector 32 connects to the operating rod 3 externally and to the collar base 41 internally. This connector 31 connects the buttons, hooks, levers, and grips on the operating handle 2 to the collar 4, clip 5, and shears 6, translating movements on the operating handle 2 into movements within the internal structure.

[0042] The connection between the operating rod 3 and the operating handle 2 can be detached, and the 2 operating handles can be replaced with existing surgical robots, and unmanned surgery can be performed by the robot. The internal control connector 32 inside the operating rod 3 can be seamlessly connected with the existing surgical robot.

[0043] The main structure inside the body is the sleeve 4, which can be divided into a sleeve base 41 and a tough, hard, multi-petal elongated cylinder 42. The sleeve base 41 is a hard cylindrical structure that is connected to the operating rod 3. The multi-petal elongated cylinder 42 has a mechanical multi-link structure 43 on its exterior that can interconnect the multiple curved petals of the multi-petal elongated cylinder 42. The rotation of the mechanical multi-link structure 43 can open and close the multiple curved petals on the multi-petal elongated cylinder 42, and can also connect the multi-petal elongated cylinder 42 as a whole to the sleeve base 41. Figure 7-9 The multi-link structure is conventional in the art.

[0044] The operation of the operating handle 2 can be transmitted to the multi-petal structure long cylinder 42 through the internal control connector 32 to control the rotation of the mechanical multi-link structure to control the infinite opening and closing of the multi-petal structure long cylinder 42.

[0045] A clamp 5 and a cutter 6 are also provided inside the sleeve 4, wherein the clamp 5 and the cutter 6 are both hard structures, the clamp 5 includes a front end clamping part and a rear end clamping part connecting part 51, and the cutter includes a front end shearing part and a rear end shearing part connecting part, and the above-mentioned connecting parts are respectively connected to the internal control connecting part 32 of the sleeve base 41.

[0046] The operation of the operating handle 2 can be transmitted to the clamp 5 and the shear 6 through the internal control connection 32 to control the extension, retraction, clamping, and release of the clamp 5 and the shearing action of the shear 6.

[0047] The clamping fingers of the clamp 5 can output a force sufficient to clamp and fix the human tissue to be removed.

[0048] The shears 6 are double-edged structures with sharp internal edges, which can evenly shear the human tissue to be removed.
