Description

Abdominal cavity tumor crushing and sucking device and method

Technical Field

The invention belongs to the technical field of minimally invasive excision of abdominal tumors, and particularly relates to an abdominal tumor aspiration device and method.

Background

Currently, minimally invasive excision of tumors in the abdominal cavity is mostly performed by:

cutting the abdomen of the patient and puncturing three sleeves to establish an instrument access channel;

and respectively inserting a laparoscope, a minimally invasive shear, a minimally invasive embedding clamp or a minimally invasive cutting flusher or an ultrasonic knife into the three cannulas to realize cutting, coagulation and taking out of target tissues.

When the cut tissue is a small-volume malignant tumor, the ultrasonic knife and other instruments can ensure that the cut part does not bleed or the bleeding amount is small, and the bleeding point of the cut malignant tissue is coagulated, so that the cut malignant tissue can be taken out by using the minimally invasive forceps.

However, when the cut tissue is a large-volume malignant tumor, the cut tumor cannot be directly taken out because the tissue is large and limited by the inner diameter of the sleeve, and the cut tumor is firstly cut into a plurality of pieces of trivia tissue suitable for passing through the sleeve and then is respectively clamped by a minimally invasive forceps holder for taking out.

In the cutting process, blood with lesion factors and tumor tridymite tissues can scatter into the abdominal cavity and cannot be thoroughly removed, so that the problem of large-area recurrence of tumors in the abdominal cavity is caused. In order to avoid the problem, the prior art mainly puts into the abdominal cavity accommodating bag through the instrument access channel formed by the sleeve and expands the abdominal cavity accommodating bag, then cuts off a large-volume tumor, clamps and transfers the tumor into the accommodating bag, and then cuts up the tumor and aspirates the tumor through the instrument access channel into the accommodating bag.

Although the prior art can avoid blood and tumor tridymite tissue with pathological factors from scattering into the abdominal cavity to some extent, the following defects still exist:

first, hold the bag and pass through the instrument business turn over passageway and throw in, prop open, shift and take out slow loaded down with trivial details operation, consuming time is long, inefficiency.

Second, the containment bag is always in a collapsed free-sagging condition, and the existence and weight of the resected tumor is limited, not only is the operational space of the tumor aspiration device within the bag inconveniently restricted and the risk of lacerating the containment bag created, but the mouth of the containment bag is open relative to the abdominal cavity, thereby resulting in the inability to completely avoid scattering of blood and tumor trix tissue with diseased factors from the abdominal cavity.

In summary, the existing abdominal cavity tumor aspiration technology has the technical problems of inconvenient operation, tedious and low efficiency and easy scattering of tumor fragments into the abdominal cavity.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

In order to solve the technical problems of inconvenient operation, tedious and low efficiency and easy scattering of tumor fragments into the abdominal cavity in the existing abdominal cavity tumor aspiration technology, referring to fig. 1-6, a basic embodiment of the invention provides an abdominal cavity tumor aspiration device, which comprises: the inner needle 1, the accommodating bag 5, the hollow tube 2, the memory guide wire 6, the air valve 4, the movable clamp tube 3, the transition ring 8, the auxiliary stay wire 7 and the sealing ring 9.

On the one hand, referring to fig. 1, 2 and 5, the inner needle 1 includes a needle tube body 10, and the needle tube body 10 is movably accommodated in the hollow tube 2.

After the aspiration device for the tumor in the abdominal cavity punctures into the abdominal cavity of the patient, the inner needle 1 can be pushed in the direction of the abdominal cavity of the patient, so that a part of the needle tube body 10 of the inner needle 1 enters the abdominal cavity of the patient. In addition, the needle tube body 10 of the inner needle 1 may be pulled out in a direction outside the abdominal cavity of the patient.

Specifically, referring to fig. 2 and 5, the needle tube body 10 may be provided as a hollow tube body, and the receiving groove 100 may be formed by cutting a sidewall of the bottom end of the hollow tube body. The accommodating groove 100 may accommodate a portion of the accommodating bag 5, and another portion of the accommodating bag 5 may be accommodated inside the hollow tube.

When the needle tube body 10 is configured as a hollow tube body, the needle tube body is mainly used for accommodating the accommodating bag 5 with a larger volume so as to adapt to specific operation requirements. The remaining portion of the accommodation groove 100 accommodated may be accommodated inside the hollow pipe body communicating with the accommodation groove 100.

Specifically, referring to fig. 1, 2, 3 and 5, the inner needle 1 further includes: the device comprises a shell 11, a base 12, an elastic piece 13 and a press button 14.

The housing 11, the base 12, the elastic member 13, and the push button 14 are provided together at the top end of the needle tube body 10, and can be locked with the top end of the hollow tube 2 by the lock catch 111, thereby realizing free assembly and disassembly of the inner needle 1 and the hollow tube 2. When the lock catch 111 is unlocked from the hollow tube 2, the inner needle 1 can be withdrawn from the hollow tube 2.

In addition, the housing 11 may be provided in a semi-elliptical shape.

In addition, the elastic member 13 may be a spring. The elastic member 13 is in an expanded state when not receiving the pressure of the press button 14, and pulls the needle tube body 10 into the hollow tube 2. The elastic member 13 is compressed when receiving the pressure of the knob 14, and presses the needle tube body 10 out of the hollow tube 2 by a predetermined stroke. Since the push button 14 passes through the constraining slide rail 110 and moves in the hole in a limited manner, the length of the constraining slide rail 110 limits the movement stroke of the push button 14, and the movement stroke of the push button 14 determines the predetermined stroke of the needle tube body 10 extruding the hollow tube 2.

In addition, since the inner needle 1 can be withdrawn from the top end of the hollow tube 2 and the needle tube body 10 thereof can be pressed out of the bottom end of the hollow tube 2 by a predetermined stroke, the needle tube body 10 is movably accommodated in the hollow tube 2.

It should be noted that, the flexible connection of the memory guide wire 6 at the mouth of the accommodating bag 5 means that when the accommodating bag 5 is folded, the memory guide wire 6 is folded and is in a contracted state. When the receiving bag 5 enters the abdominal cavity of the patient, the memory guidewire 6 stretches to open the mouth of the receiving bag 5.

The memory guidewire 6 is a slender and tensile wire-like substance which can be deformed arbitrarily when compressed by an external force and which returns to its original shape when the external force is released.

On the other hand, referring to fig. 1, 2, 3 and 5, the hollow tube 2 can be used for the inner needle 1 to move and withdraw, and the inner needle 1 can be used for moving to drive the accommodating bag 5 to separate from the hollow tube body.

The hollow tube 2 is sleeved outside the inner needle 1. Pushing the inner needle 1 can drive the holding bag 5 to separate from the hollow tube. Pulling the inner needle 1 can pull the inner needle 1 out of the hollow tube 2.

Specifically, the top end of the hollow tube 2 is provided with an upper cover 20, and the top end of the upper cover 20 is provided with a groove (not shown) for locking with the lock catch 111.
