Description

Anastomotic stoma reinforcement repair sheet and surgical device

Technical Field

The present disclosure relates to the field of medical devices, and in particular, to a stoma reinforcement repair patch and a surgical device.

Background

The application of the anastomat can greatly promote the development of modern surgery and minimally invasive surgery, and has the significance of milestones. The anastomat can staple tissues through the anastomat during cutting, and is widely used for cutting, suturing or anastomosis of visceral tissues such as intestines, stomach, lung, pancreas and the like. However, the defects, leakage and bleeding of the tissue of the anastomotic stoma cannot be completely avoided by combining the hard nails of the anastomotic nail, and the problems of infection, stenosis, scarring and the like can be caused. Once complications such as anastomotic leakage, bleeding, stenosis, infection, adhesion and the like occur, secondary surgery may be required to solve, seriously affecting the quality of life of the patient, and even endangering life, causing serious economic and psychological burden to the patient.

The prior art methods use staplers with a sheet of biomaterial in order to reduce the complications after anastomosis. The nail bin and the nail anvil surface of the anastomat are both provided with a layer of absorbable biological material membrane, and the biological material membrane is fixed on the anastomat opening when the stapling and cutting are finished, so that fragile tissues are protected from being torn by the anastomat, or gaps between bare nails and tissues or blood vessels are closed, thereby strengthening the anastomat opening and reducing the risks of complications such as anastomotic leakage, bleeding and the like. The biological material membrane is a sheet structure made of degradable biological material, and the degradable biological material can be a high polymer material or an animal tissue material. Preferably, the degradable biological material may be an animal-derived tissue material, such as a submucosa material, preferably a small intestine submucosa material, a urinary bladder submucosa material, subjected to an immunogen removal treatment; or for example, an organ envelope, preferably a pericardium.

However, prior methods require the reinforcement patches of the stoma to be assembled to the cartridge portion and anvil portion of the cartridge assembly of the stapler, typically by detachably connecting the reinforcement patches to the backing using wires, and then assembling the reinforcement patches to the cartridge portion and anvil portion together. However, since the reinforcing repair sheet is generally made of a flexible material, during the assembly process of the reinforcing repair sheet, the reinforcing repair sheet is often not assembled to a predetermined position of the backing, or the reinforcing repair sheet protrudes from a structural gap in the backing due to an operation reason of an operator and a structural reason between the reinforcing repair sheet and the backing.

In addition, after the reinforcing patch is fixed to the tissue to be treated, the fixation between the reinforcing patch and the backing may be released by removing the wires, thereby removing the backing. However, the adoption of the wire fixing biological material layer and the back lining makes the structure of the reinforcing repair sheet complex, and special placement and fixing are needed to be carried out so as to cooperate with the anastomat to ensure that the wire is not knotted or confused, thereby increasing the process steps in the process of manufacturing the product and influencing the production efficiency and the yield of the product.

In addition, since the staples need to completely cover the area of the reinforcement patch in contact with the tissue, the total length of the staple along the stoma reinforcement patch needs to be greater than the length of the patch. In other words, the staple line distal length is greater than the cut line length. However, in the structure of the existing reinforced repair sheet, the existing cutter is likely to fail to cut the repair sheet, and the cutting operation is completed only by means of other cutting tools, which increases the operation complexity.

Therefore, there is a need for a stoma-strengthening repair sheet with an improved structure that more effectively cooperates with a stapler to solve the above-described problems.

The improved structure of the present utility model will be specifically described below.

Fig. 1 is a schematic perspective view of an example of a stoma reinforcement repair patch provided in the present disclosure.

As shown in fig. 1, the present disclosure provides a stoma-strengthening repair patch 10, the stoma-strengthening repair patch 10 (also referred to as a first stoma-strengthening repair patch 10 in this embodiment) comprising a first sheet of biomaterial 11 and a first backing 13 detachably connected to the first sheet of biomaterial 11.

Fig. 2 is a perspective exploded view of an example of the stoma reinforcement repair patch of fig. 1.

As shown in fig. 2, the first biomaterial membrane sheet 11 includes a first main body 111, a first extension 113 extending outwards from the main body 111, and a first notch 115 is formed at one end of the first biomaterial membrane sheet 11, wherein the first main body 111 is substantially strip-shaped, and an orthographic projection on a plane parallel to a horizontal plane is substantially rectangular, but not limited thereto, and in other examples, the orthographic projection may be a chamfered rectangle or other polygonal shape. The foregoing is illustrative only and is not to be construed as limiting the utility model.

In the present utility model, an end of the component or the member on the left side of the drawing sheet is referred to as a first end, an end of the component or the member on the right side of the drawing sheet (i.e., an end opposite to the first end) is referred to as a second end, an upper side of the drawing sheet is referred to as an upper side, and a lower side of the drawing sheet is referred to as a lower side.

Specifically, a first extension portion 113 is provided at a first end of the first body portion 111, that is, the first extension portion 113 is formed to extend outwardly from a portion (in this example, a central portion) of the first end of the first body portion 111. More specifically, the first extension 113 is inclined outward from the first body 111, for example, downward and leftward as shown in fig. 2.

In other examples, the first inclined portion 111 may be located on the same horizontal plane as the first main body portion 111. The shape of the first extension portion is not particularly limited, as long as the shape is easily pluggable. The foregoing is illustrative only and is not to be construed as limiting the utility model.

In the example shown in fig. 2, the first cutout 115 is provided at the first extension 113 and partially provided at the first main body 111, and the first cutout 115 is provided along the length direction of the first main body 111. As can be seen from fig. 2, the first extension 113 is divided into two parts by the first cutout 115.

Further, a first cap 130 is provided at one end of the first backing 13, and the first cap 130 has a receiving space S1 for receiving the first extension 113.

Optionally, the depth d1 of the accommodating space S1 of the first cap 130 is smaller than or equal to the length c of the first extension 113 in the length direction of the first biomaterial membrane sheet 11, as can be seen in fig. 2.

Preferably, the depth d1 of the accommodating space S1 of the first cap 130 is less than or equal to 1/2 of the length c of the first extension 113 in the length direction of the first biological material membrane 11.

It should be noted that the foregoing is merely illustrative of the present utility model and is not to be construed as limiting thereof.

Fig. 3 is a perspective exploded view of an application example of the stoma reinforcement repair patch of fig. 1. FIG. 3 illustrates the present utility model of a stoma reinforcement repair in combination with a staple cartridge assembly of a stapler. The improved structure of the stoma reinforcement patch of the utility model will be further described below in connection with the application example of fig. 3.

Referring to fig. 1 and 3, in the case that the first stoma-reinforcing repair sheet 10 is used in cooperation with the cartridge assembly 20 of the stapler 200, at least a portion of the first extension portion 113 is inserted into the first cap portion 130, and the first biomaterial film sheet 11 and the first backing 13 are detachably sewn together by the wire 60 to form a first socket structure, and the first socket structure is socket-coupled with the cartridge assembly 30 of the stapler 200 to form the first stoma-reinforcing repair sheet in a first use state.

Specifically, by providing the first cap 130 on the first backing 13 and providing the depth of the accommodating space S1 of the first cap 130, so that at least a portion of the first extension 113 is inserted into the first cap 130, that is, by using the structure that the first cap 130 accommodates the first extension 113, the insertion of the first biomaterial film into the first cap can be effectively ensured.

Further, by inserting a portion of the first extension 113 into the first cap 130 and detachably jointing the first biomaterial membrane 11 and the first backing 13 with the wire 60 to form a first sleeve structure, the insertion of the first biomaterial membrane into the first cap can be more effectively ensured, and further, the problem of incorrect operation or assembly dislocation caused by the fact that the biomaterial membrane is not assembled to a preset position of the backing, or the biomaterial membrane protrudes from a structural gap in the backing, and the repairing and anastomosis of an anastomosis can be directly performed after cutting.

In addition, a first incision 115 is further provided on the first main body 111, where the first incision 115 is used to cooperate with the cutting assembly 50 of the anastomat 200, and the cutting position of the cutting assembly during the cutting treatment of the tissue to be treated is limited by the first incision 115, so that the position reached by the first end of the cutting assembly (i.e. the front end that is firstly contacted with the tissue to be treated when in use) coincides with the preset cutting position, which can ensure that the cutting assembly completely cuts off the reinforcement repair sheet, and at the same time can ensure the complete anastomosis of the anastomotic orifice, without using an additional cutting tool, thereby improving the operation convenience.

Fig. 4 is a schematic view of another example of the stoma reinforcement repair patch of fig. 1.

The example of fig. 4 differs from the example of fig. 3 in that the first body portion 111 of the first sheet of biomaterial 11 is provided with a first guide opening 117 at a second end opposite to the first end.

Specifically, the first guide opening 117 is a through hole penetrating the first body 111, and a center line of the first guide opening 117 along the longitudinal direction of the first body 111 coincides with a center line of the first cutout 115 along the longitudinal direction of the first body 111. The first guiding opening 117 is used for guiding the cutting assembly of the anastomat to perform cutting operation, so that the shearing force of the cutting assembly when cutting the repair patch can be reduced, and the risk of unfavorable cutting caused by curling of the repair patch is avoided.

Note that, since the first backing in the example of fig. 4 is substantially the same as the first backing in fig. 1 in structure, the description of the same portions thereof is omitted.

Example 2

Another example of the stoma reinforcement patch of the utility model will be described with reference to fig. 5 to 9.

It should be noted that, in this embodiment, the stoma reinforcement repair sheet (also referred to as a second stoma reinforcement repair sheet 20 in this embodiment) is used in combination with an anvil assembly of the stapler.

Fig. 5 is a perspective structural entity view of another example of a stoma reinforcement repair patch provided by the present disclosure. Fig. 6 is a perspective exploded view of the anastomosis reinforcing repair sheet of fig. 5.

As shown in fig. 5 and 6, the second stoma reinforcement repair patch 20 includes a second biomaterial membrane sheet 21 and a second backing 23, the second backing 23 being detachably connected to the second biomaterial membrane sheet 21.

Alternatively, the second biomaterial membrane sheet 21 and the second backing 23 are detachably connected by a wire 61, and specifically, both sides in the width direction of the second biomaterial membrane sheet 21 and both sides in the width direction of the second backing 23 are detachably connected by the wire 61 along the length direction of the second biomaterial membrane sheet 21.

Specifically, the second biomaterial membrane 21 includes a second body 211, and a second extension 213 extending from the second body 211, wherein the second extension 213 is divided into two parts by the second slit 215, i.e., the second extension 213 is two protruding parts protruding from the second body 213.

Further, one end (i.e., the first end) of the second backing 23 is provided with a second cap 230, and the second cap 230 has a receiving space S2 for receiving the second extension 213.

Optionally, the depth d2 of the accommodating space S1 of the second cap 230 is smaller than or equal to the length c2 of the second extension 213 in the length direction of the second biomaterial membrane sheet 11, as can be seen in fig. 6.

Preferably, the depth d2 of the receiving space S1 of the second cap 230 is less than or equal to 1/2 of the length c2 of the second extension 213 in the length direction of the second biomaterial membrane sheet 11.

In assembled use, at least a portion of the second extension 213 is inserted into the second cap 230 and the second biomaterial membrane 21 and the second backing 23 are detachably stitched by wire 61 to form a second socket (see fig. 7).

Note that the second biomaterial film sheet 21 and the second backing 23 in the example shown in fig. 5 have substantially the same structure as the first biomaterial film sheet 11 and the first backing 13 in the example shown in fig. 1, and the second biomaterial film sheet 21 in embodiment 2 has substantially the same functions and preparation materials as the first biomaterial film sheet 11 in embodiment 1, and therefore, the description of the same parts thereof is omitted.

Fig. 7 is a schematic perspective view of another application example of the stoma reinforcement repair patch of fig. 5.

Fig. 7 shows the present utility model of a stoma reinforcement repair (i.e. a second stoma reinforcement repair) in combination with an anvil assembly of the stapler.

As shown in fig. 7, in the case that the second stoma reinforcement repair sheet 20 is used in cooperation with the anvil assembly 40 of the stapler 200, at least a portion of the second extension portion 213 is inserted into the second cap portion 230, and the second biomaterial membrane 21 and the second backing 23 are detachably sewn together by the wire 61 to form a second socket structure, and the second socket structure is socket-connected to the anvil assembly 40 of the stapler 200 to form the stoma reinforcement repair sheet in the second use state.

Through the second sleeving structure, the second biological material membrane can be more effectively ensured to be inserted into the second cap part, and further, the problem that the biological material membrane is not assembled to the preset position of the back lining, or the biological material membrane stretches out of a structural gap in the back lining and other misoperation or assembly dislocation problems are more effectively avoided, and the reinforcement repair and anastomosis of an anastomotic stoma can be directly carried out after cutting.

Alternatively, the length a of the second cutout 215 in the length direction of the second body portion 211 is smaller than 1/2 of the length b of the second body portion 211 in the length direction thereof, as can be seen in particular in fig. 8.

Preferably, the length a of the second cutout 115 in the length direction of the second body portion 211 is less than 1/2 of the length b of the second body portion 211 in the length direction thereof.

Through the setting of second incision and length, can further guarantee that cutting assembly cuts off the reinforcement repair piece completely, can guarantee simultaneously that the anastomotic stoma's is completely anastomotic, and need not to use extra cutting tool and then can improve the operating convenience.

Fig. 8 is a schematic view of another example of the stoma reinforcement repair patch of fig. 5.

The example of fig. 8 differs from the example of fig. 5 in that the second body portion 211 of the second biomaterial membrane 21 is provided with a second guide opening 217 at a second end opposite to the first end.

Specifically, the second guide opening 217 is a through hole penetrating the first body 211, and the position of the second guide opening 217 corresponds to the position of the first guide opening 117.

Further, the center line of the second guide opening 217 along the length direction of the second body 211 coincides with the center line of the second slit 215 along the length direction of the second body 211. The second guiding opening 217 is used for guiding the cutting assembly of the anastomat to perform cutting operation, so that the shearing force of the cutting assembly when cutting the repair patch can be further reduced, and the risk of unfavorable cutting caused by curling of the repair patch is avoided.

Example 3

The utility model also provides a surgical device for cutting, anastomosis and the like of the tissue to be treated. The surgical device of the present utility model will be described with reference to fig. 1, 3, 5, 7 and 9.

In the first embodiment, the stoma reinforcement repair is the first stoma reinforcement repair 11 in example 1. I.e., the stoma strengthening repair is only used to socket the cartridge assembly 30, see in particular fig. 3.

As shown in fig. 3, in the case that the first stoma reinforcement repair sheet 11 is used in cooperation with the cartridge assembly 30 of the stapler 200, at least a portion of the first extension portion 113 is inserted into the first cap portion 130, and the first biomaterial membrane 11 and the first backing 13 are detachably sewn together by the wire 60 to form a first sleeve structure, and the first sleeve structure is sleeve-jointed with the cartridge assembly 30 of the stapler 200 to form the stoma reinforcement repair sheet in the first use state.

Furthermore, a first incision 115 is provided in the first body portion 111, said first incision 115 being intended to cooperate with the cutting assembly 50 of the stapler 200.

Specifically, the length of the first cutout 115 in the length direction of the first main body portion 111 is less than 1/2 of the length of the first main body portion 111 in the length direction thereof.

Preferably, the length of the first cutout 115 in the length direction of the first body portion 111 is less than 1/3 of the length of the first body portion 111 in the length direction thereof.

The first incision 115 limits the cutting position of the cutting assembly during the cutting treatment of the tissue to be treated, so that the position reached by the first end of the cutting assembly (i.e., the front end that is first contacted with the tissue to be treated when in use) coincides with the preset cutting position, thereby ensuring that the cutting assembly completely cuts off the reinforcement repair sheet, and simultaneously ensuring the complete anastomosis of the anastomotic stoma without using an additional cutting tool, and further improving the convenience of operation.

Note that, since the structure of the first anastomosis reinforcing repair sheet 11 in the first embodiment is substantially the same as that of the first anastomosis reinforcing repair sheet 11 in example 1, the description of the same portions thereof is omitted.

In the second embodiment, the stoma reinforcement repair is the second stoma reinforcement repair 21 in example 2. I.e., the stoma strengthening repair is only used to socket anvil assembly 40, see in particular fig. 7.

As shown in fig. 7, in the case that the second stoma-reinforcing repair sheet 20 is used in cooperation with the anvil assembly 40 of the stapler 200, at least a portion of the second extension portion 213 is inserted into the second cap portion 230, and the second biomaterial membrane 21 and the second backing 23 are detachably sewn together by the wire 61 to form a second socket structure, and the second socket structure is socket-coupled with the anvil assembly 40 of the stapler 200 to form the stoma-reinforcing repair sheet in the second use state.

Note that, since the structure of the second anastomosis reinforcing repair sheet 20 in the second embodiment is substantially the same as that of the second anastomosis reinforcing repair sheet 21 in example 2, the description of the same portions thereof is omitted.

In the third embodiment, the anastomotic stoma reinforcement patch includes the first anastomotic reinforcement patch 11 in example 1 and the second anastomotic reinforcement patch 21 in example 2, that is, the anastomotic stoma reinforcement patch is used for sleeving the cartridge assembly 30 and the anvil assembly 40, and particularly, see fig. 9.

As shown in fig. 9, in the case that the first stoma reinforcement repairing sheet 11 is used together with the cartridge assembly 30 of the stapler 200, and the second stoma reinforcement repairing sheet 20 is used together with the anvil assembly 40 of the stapler 200, the first biomaterial membrane sheet 11 and the first backing 13 are detachably sewn together by the wire 60 to form a first sleeve structure, and the second biomaterial membrane sheet 21 and the second backing 23 are detachably sewn together by the wire 61 to form a second sleeve structure.

Specifically, at least a portion of the first extension 113 is inserted into the first cap 130, and the first sheet of biomaterial 11 and the first backing 13 are detachably joined by the wire 60 to form a first sleeve structure, which is sleeved on the cartridge assembly 30 of the stapler 200 to form the stoma-strengthening repair sheet in the first use state. And, at least a portion of the second extension 213 is inserted into the second cap 230, and the second biomaterial membrane 21 and the second backing 23 are detachably sewn together by the wire 61 to form a second sleeve structure, and the second sleeve structure is sleeved on the anvil assembly 40 of the stapler 200 to form a stoma reinforcing repair sheet in a second use state.

In this third embodiment, the second biomaterial membrane 21 is provided with the second incision 215 corresponding to the position of the first incision 115, and the first incision and the second incision corresponding to the positions cooperate with the cutting assembly of the anastomat together to perform related operations, so that the cutting assembly can be further ensured to completely cut off the reinforcement repair sheet, and meanwhile, the complete anastomosis of the anastomotic stoma can be ensured, without using an additional cutting tool, and thus, the operation convenience can be improved.

Regarding the lengths of the first cutout 115 and the second cutout 215, the length of the first cutout 115 in the length direction of the first body portion 111 is equal to the length of the second cutout 215 in the length direction of the second body portion 211.

In another embodiment, a first guide opening 117 is provided at a second end of the first body portion 111 opposite to the first end, and a second guide opening 217 corresponding to the position of the first guide opening 117 is provided at the second body portion 211.

In this embodiment, the center line of the first guide opening 117 in the longitudinal direction of the first biomaterial membrane sheet 11 (i.e., the first body portion 111) coincides with the center line of the first slit 115 in the longitudinal direction of the first biomaterial membrane sheet (i.e., the first body portion 111). Accordingly, the center line of the second guide opening 217 in the length direction of the second biomaterial membrane sheet 21 (i.e., the second body portion 211) coincides with the center line of the second slit 215 in the length direction of the second biomaterial membrane sheet 21 (i.e., the second body portion 211).

Compared with the prior art, the surgical device can effectively avoid the misoperation problems such as the unassembled biological material membrane to the preset position of the back lining or the extension of the biological material membrane from the structural gap in the back lining or the assembly dislocation problem by improving the structure of the anastomotic stoma reinforcing and modifying sheet, and can also directly perform the reinforcing, repairing and anastomosis of the anastomotic stoma after cutting; the cutting position of the cutting assembly of the anastomat during cutting treatment of tissues to be treated and the like is limited through the incision, so that the position reached by the first end of the cutting assembly (namely, the front end firstly contacts the tissues to be treated during cutting treatment) coincides with the preset cutting position, the cutting assembly can be ensured to completely cut off the reinforcing repair piece, meanwhile, the complete anastomosis of an anastomotic stoma can be ensured, and an additional cutting tool is not required, so that the operation convenience can be improved; by arranging the guide opening on the reinforcing repair piece, the shearing force of the cutting assembly when cutting the repair piece can be reduced, and the risk that the repair piece is curled to generate unfavorable cutting is avoided.
