Description

A COMPOSITE POLYPECTOMY DEVICE

TECHNICAL FIELD

[001] The present disclosure generally relates to the field of medical devices. More particularly, the present disclosure relates to a composite polypectomy device that makes the polypectomy procedure more efficient.

BACKGROUND

[002] Gastrointestinal polyps have potential to turn cancerous and their identification and resection through polypectomies are routinely carried out. Polyps are varied in size and shape and may be located in regions that are difficult to access through endoscopy. Polypectomies are either "cold" mechanical cutting or "hot" resection through electrocautery. Various types of devices like snares and forceps are available for performing polypectomies and each of them have their own advantages and disadvantages.

[003] During polypectomy with a snare, the snare device is guided to the location through an endoscope after which snaring of the polyp is done. In hot snare technique, the snare is tightened around the polyp and through electrocauterization, the polyp is resected with minimal bleeding. In the same way, forceps are guided endoscopically and sampling or ablation/resection of the polyp is carried out. But the process of grasping/snaring the polyp is often difficult and time consuming for the doctor particularly when the polyp is located in regions that are hard to access and for trainees and endoscopists who have less expertise.

[004] In the light of aforementioned discussion, there exists a need for a medical device that eases the process of grasping/snaring the polyp thus making polypectomy procedures more efficient. The present invention discloses a composite polypectomy device comprising a snare device or an endoloop applicator and a forceps that makes the polypectomy procedure efficient.

[041] Referring to FIG. 9B, it is a schematic representation of the ensnaring and tightening of the polyp by the detachable snare loop in the composite polypectomy device, in accordance with a non limiting exemplary embodiment of the present disclosure.

[042] According to a non limiting exemplary embodiment of the present disclosure, a composite polypectomy device 100 comprising a snare device 101 and a forceps 102 is disclosed. This composite polypectomy device 100 is coaxially slidable within a channel of an endoscopic device 402 and the dimensions of the composite polypectomy device 100 are such that it can be accommodated and operated with ease through any channel of the endoscopic device 402.

[043] In accordance with a non limiting exemplary embodiment of the present disclosure, a composite polypectomy device 100 comprising a snare device 101 and a forceps 102 is disclosed, wherein the forceps 102 is designed to grasp a polyp 401 as well as to electrocoagulate for hemostasis, if there is bleeding during the polypectomy procedure.

[044] In accordance with a non limiting exemplary embodiment of the present disclosure, a composite polypectomy device 100 comprising a snare device 101 and a forceps 102 is disclosed, wherein the composite polypectomy device 100 has a longitudinal tubular flexible body 103 with a first end that is proximal to the handles of the snare device 101 and the forceps 102 and a second end that is proximal to the polyp 401 to be resected during the operative process. The longitudinal tubular flexible body 103 has a first conduit and a second conduit that are hollow and are longitudinally parallel to each other for accommodating the snare device 101 and the forceps 102 respectively. The snare device 101 and the forceps 102 are coaxially slidable relative to their respective conduits and can be replaced as and when required.

[045] In accordance with a non limiting exemplary embodiment of the present subject matter, the snare device 101 has a proximal end that is proximal to a snare handle 104 and a distal end from where a snare loop 204 is extended or retracted during the polypectomy procedure. The snare handle 104 is operatively connected to the longitudinal, flexible tubular body member 201 of the snare device 101 which comprises of a longitudinal tubular shaft 203 that is enclosed within an outer sheath 202. The longitudinal tubular shaft 203 is coaxially slidable relative to the outer sheath 202. A collapsible snare loop 204 is attached to the distal end of the longitudinal tubular shaft 203. The operation of the snare handle 104 coordinates the to and fro movement of the outer sheath 202 as well as the longitudinal tubular shaft 203 causing the extension and retraction of the snare loop 204.

[046] According to a non limiting exemplary embodiment of the present disclosure, the forceps 102 comprises of a forceps handle 105 operatively connected to a longitudinal cable 301 enclosed within a longitudinal flexible tubular cable sheath 302. The cable 301 at its proximal end is coupled to the forceps handle 105 and at its distal end is connected to a forceps assembly 303, wherein the forceps assembly 303 comprises of a pair of jaws 304 articulably opposed to each other. The forceps handle 105 when operated causes the to and fro movement of the cable 301 leading to pushing up and extension of the jaws 304 or pulling down and retraction of the jaws 304.

[047] In accordance with a non limiting exemplary embodiment of the present disclosure, the snare device 101 and the forceps 102 of the composite polypectomy device 100 can be used for "hot" cauterization as well as "cold" mechanical cutting. The device can be used for collection of samples for biopsy purposes or for resection/ablation of polyps.

[048] Polypectomy procedure is difficult to learn, requiring training and skills in instrument handling including the ability to efficiently and precisely control the endoscope tip and therapeutic devices. Removal of polyps during polypectomy is sometimes quite difficult and tedious procedure. The composite polypectomy device considerably simplifies the procedure. At first, the snare device 101 and the forceps 102 are inserted into the first conduit and the second conduit respectively of the composite polypectomy device 100. Then the snare loop 204 is ensnared and tightened over the forceps assembly 303 before insertion of the composite polypectomy device 100 into the working channel of an endoscopic device 402. The working channel of the endoscopic device 402 is used to bring the device in proximity with the polyp 401. This helps in estimating the size of polyp 401. Subsequently, forceps 102 is used to grasp the polyp 401, over which the snare loop 204 is later advanced over the forceps 102, which has already been positioned above the level of forceps assembly 303, to ensnare the polyp 401. Subsequently, the snare loop 204 is tightened over the peduncle/base of the polyp 401. It ensures that the polyp 401 is ensnared. The extent of opening of the pair of jaws 304 of the forceps assembly 303 and the advancement of the snare loop 204 can be controlled by to and fro movements of corresponding handles of the device. Once the polyp 401 has been ensnared, sampling or resection is done by "cold" mechanical cutting or through "hot" electro cauterisation.

[049] According to a non limiting exemplary embodiment of the present disclosure, a composite polypectomy device 500 comprising an endoloop applicator 501 and a forceps 502 is disclosed. This composite polypectomy device 500 is coaxially slidable within a channel of an endoscopic device 902 and the dimensions of the composite polypectomy device 500 are such that it can be accommodated and operated with ease through any channel of the endoscopic device 902.

[050] In accordance with a non limiting exemplary embodiment of the present disclosure, a composite polypectomy device 500 comprising an endoloop applicator 501 and a forceps 502 is disclosed, wherein the forceps 502 is designed to grasp a polyp 901 as well as to electrocoagulate the base of the polyp 901 for hemostasis, if there is bleeding during the polypectomy procedure.

[051] In accordance with a non limiting exemplary embodiment of the present disclosure, a composite polypectomy device 500 comprising an endoloop applicator 501 and a forceps 502 is disclosed, wherein the composite polypectomy device 500 has a longitudinal tubular flexible body 503 with a first end that is proximal to the handles of the endoloop applicator 501 and the forceps 502 and a second end that is proximal to the polyp 901 to be resected during the operative process. The longitudinal tubular flexible body 503 has a first conduit 506 and a second conduit 507 that are hollow and are longitudinally parallel to each other for accommodating the endoloop applicator 501 and the forceps 502 respectively. The first conduit 506 and the second conduit 507 are separated by a septum 601.

[052] In accordance with a non limiting exemplary embodiment of the present subject matter, the endoloop applicator 501 has a proximal end that is proximal to a snare handle 504 and a distal end from where a detachable snare loop 702 is extended or retracted during the polypectomy procedure. The snare handle 504 is operatively connected to the longitudinal, flexible tubular body member 701 of the endoloop applicator 501 which comprises of a longitudinal tubular shaft 604 that is enclosed within an outer sheath 603. The longitudinal tubular shaft 604 is coaxially slidable relative to the outer sheath 603. A collapsible and detachable snare loop 702 is attached to the distal end of the longitudinal tubular shaft 604 by means of a hook 704. The detachable snare loop 702 further comprises of a stopper 703 near one end of the loop that is configured to prevent the snare loop 702 from being pulled inside the lumen of the endoloop applicator 501. The operation of the snare handle 504 coordinates the to and fro movement of the outer sheath 603 as well as the longitudinal tubular shaft 604 causing the extension and retraction of the snare loop 702 as well as the detachment of the snare loop 702 once it is snared around the polyp 901. In a particular embodiment, the detachable snare loop 702 is a rotatable snare loop configured to rotate up to 360 degrees to tackle hard to access polyps.

[053] According to a non limiting exemplary embodiment of the present disclosure, the forceps 502 comprises of a forceps handle 505 operatively connected to a longitudinal cable 602 enclosed within a longitudinal flexible tubular cable sheath 801. The longitudinal cable 602 at its proximal end is coupled to the forceps handle 505 and at its distal end is connected to a forceps assembly 802, wherein the forceps assembly 802 comprises of a pair of jaws 803 articulably opposed to each other. The forceps handle 505 when operated causes the to and fro movement of the longitudinal cable 602 leading to pushing up and extension of the jaws 803 or pulling down and retraction of the jaws 803.

[054] In accordance with a particular non limiting exemplary embodiment of the present disclosure, the forceps 502 of the composite polypectomy device 500 does not have the longitudinal flexible tubular cable sheath and instead the wall of the second conduit 507 of the device directly encloses the longitudinal cable 602 of the forceps 502 thus making the device more compact. The cross section and longitudinal section of such a composite polypectomy device is depicted in FIG. 6A and FIG. 6B respectively. [055] According to a non limiting exemplary embodiment of the present disclosure, the endoloop applicator 501 and the forceps 502 are coaxially slidable relative to their respective conduits in the composite polypectomy device 500 and can be replaced as and when required.

[056] In accordance with a non limiting exemplary embodiment of the present disclosure, the endoloop applicator 501 and the forceps 502 of the composite polypectomy device 500 can be used for "hot" cauterization as well as "cold" mechanical cutting. The device can be used for collection of samples for biopsy purposes or for resection/ablation of polyps.

[057] The composite polypectomy device 500 considerably simplifies the procedure. At first, the detachable snare loop 702 is grasped with a hook 704 present at the distal end of the longitudinal tubular shaft 604 of the endoloop applicator 501 and then placed in a retracted position, wherein the stopper 703 present at one end of the detachable snare loop 702 prevents it from getting further retracted into the lumen of the endoloop applicator 501. Then, the endoloop applicator 501 is inserted into the first conduit 506 of the composite polypectomy device 500. In a particular embodiment, a forceps 502 is inserted through the second conduit 507 of the composite polypectomy device 500. Subsequently, the detachable snare loop 702 is ensnared and tightened over the forceps assembly 802 before insertion of the composite polypectomy device 500 into the working channel of an endoscopic device 902. The working channel of the endoscopic device 902 is used to bring the device in proximity with the polyp 901. This helps in estimating the size of polyp 901. Subsequently, the forceps 502 is used to grasp the polyp 901 and the detachable snare loop 702 is extended and advanced over the forceps 502, wherein the snare loop 702 has already been positioned above the level of forceps assembly 802, to ensnare the polyp 901. Then, the snare loop 702 is tightened over the peduncle/base of the polyp 901. It ensures that the polyp 901 is ensnared. The extent of opening of the pair of jaws 803 of the forceps assembly 802 and the advancement of the snare loop 702 can be controlled by to and fro movements of corresponding handles of the device. Once the polyp 901 has been ensnared, sampling or resection is done by "cold" mechanical cutting or through "hot" electro cauterisation. In a particular embodiment, the detachable snare loop 702 is released from the hook 704 and detached from the endoloop applicator 501 once snaring and closing of the polyp 901 is done.

[058] Cold snaring is the preferred technique for polyps smaller than 10 mm. While using cold snaring, the goal is to resect a one to two millimetre margin of normal tissue around the polyp. The snare loop 204 is gradually and completely closed in a single, continuous movement to cut the tissue. Cold snaring allows rapid and immediate visualization of the polypectomy defect after resection. The margins of the defect can be quickly inspected to confirm if complete resection has been done. There is typically minor capillary bleeding after cold resection, which is trivial and clinically insignificant. Rarely, there is profuse bleeding from the base of the defect, usually in patients with coagulopathy or those on therapeutic anticoagulation. Cold snaring helps in immediate visualization of the bleeding site which can readily be treated with electro cauterisation through the jaws 304 of the forceps assembly 303.

[059] Hot snare resection is used for polyps less than 10 mm that are narrow-based, bulky or pedunculated. These polyps are more vascular and hence have a higher chance of significant bleeding. In case of complications like post polypectomy bleeding, forceps can be used coagulate the bleeding site by electrocautery. Hot snaring can damage the normal mucosa surrounding the polyp. Hence, one should be careful while removing the polyp. It is important to hold the polyp away from the opposite intestinal wall to prevent electrocautery injury.

[060] Electrosurgical current (electrocautery) has been used in combination with mechanical transection for resection of all polyps with either snare or forceps. It ensures acute hemostasis, and thermal energy ensures obliteration of pathologic tissue around the polyp. Pure low-power coagulation provides immediate hemostasis, but carries a higher risk of thermal injury and a higher rate of delayed bleeding. On the contrary, blended current achieves effective transection with a lower depth of thermal injury and delayed bleeding. Technological advancements have brought into use new electrosurgical generators which have a microprocessor to deliver a fix amount of energy and are responsive to tissue impedance. Many endoscopists have begun to use these systems for complex polypectomy procedures.

[061] Although the present disclosure has been described in terms of certain preferred embodiments and illustrations thereof, other embodiments and modifications to preferred embodiments may be possible that are within the principles and spirit of the invention. The above descriptions and figures are therefore to be regarded as illustrative and not restrictive.

[062] Thus the scope of the present disclosure is defined by the appended claims and includes both combinations and sub combinations of the various features described herein above as well as variations and modifications thereof, which would occur to persons skilled in the art upon reading the foregoing description.
