The sponge device of the present application is particularly suitable for use in laparoscopic/robotic surgery: the sponge body is soft in material and excellent in absorption performance, and is beneficial to tissue protection, operative field exposure and compression hemostasis; the sponge body can be developed under X-rays due to the developing lines, so that the sponge body is convenient to find; due to the belt traction belt, the sponge body can be conveniently operated and moved or taken out through a puncture hole of a laparoscope, for example.
Description
Technical Field
The invention relates to the field of medical supplies, in particular to a sponge for laparoscopic/robotic surgery and a manufacturing method thereof.
Background
In the surgical operation process, an operation sponge is usually needed to absorb blood and other liquid in and around the operation position, on one hand, the operation field can be kept clean, the operation is convenient, and on the other hand, the hemostasis of the wound surface can be helped. It is also necessary to remove all surgical sponges used in the procedure from the patient at the end of the procedure or before suturing the surgical site to ensure that no surgical sponges are inadvertently left in the patient after the surgical procedure is completed.
It is therefore desirable to include radiopaque materials in surgical sponges so that visualization and positioning can be performed with X-rays. In addition, it is desirable to properly design the structure of the surgical sponge so that it can be easily removed from the body.
Disclosure of Invention
In one aspect, the present application provides a sponge for laparoscopic/robotic surgery.
Herein, the sponge for laparoscopic/robotic surgery includes a sponge body, at least one developing wire, and a traction belt, the developing wire being disposed inside the sponge body.
Optionally, the sponge for laparoscopic/robotic surgery may be wrapped with gauze.
Preferably, a pull strip is led out from one end of the sponge body to facilitate pulling the mobile sponge so that it can be manipulated, for example in the abdominal cavity, or extracted through a laparoscopic puncture.
In one embodiment, the developer wire and the pull tape are made of different materials. In another embodiment, the developing wire and the traction belt are made of the same material, the developing wire and the traction belt are integrated, and the traction belt may be an extension of the developing wire. In yet another embodiment, the development line and the traction tape are made of the same material, but the development line and the traction tape are separate.
The sponge body is a high-expansibility porous sponge which can not be absorbed by human body, is nontoxic, non-irritant and highly hydrophilic, and can be quickly expanded after absorbing liquid. Preferably, the sponge body is made of polyvinyl acetal, polyvinyl alcohol (PVF), gelatin, alkylated chitosan or Polyurethane (PU). More preferably, the material of sponge body is Polyurethane (PU), and the sponge body material that makes to PU is soft, be difficult to harden, and the absorptivity is strong, is favorable to the tissue protection.
Preferably, the sponge body contains a hemostatic and/or antimicrobial agent (or bacteriostatic agent) and thus may function to absorb fluid (e.g., blood) that flows out during surgery, stop bleeding, and/or prevent microbial infection (or bacteriostasis).
Preferably, the hemostatic agent is one or more of thrombin, prothrombin, fibrinogen, calcium chloride, calcium alginate, and animal-derived collagen; the antimicrobial agent is one or more of sulfadiazine, triclosan and mupirocin.
Preferably, the sponge body has a water absorption thickness expansion ratio of 3 times or more, preferably 5 times or more, measured after being immersed in water for 5 seconds. The water absorption thickness expansion rate can be measured according to a standard method commonly used in the art. Herein, the water absorption thickness expansion rate is measured as follows: a dried sponge sample having a length of 2cm x a width of 1cm x a thickness of 0.5cm was cut at room temperature (25 ℃), immersed in a sufficient amount of distilled water so that the distilled water completely submerged in the sponge sample, and after 5 seconds of immersion, the thickness of the sponge sample after water absorption was measured, and the water absorption thickness expansion ratio (i.e., the thickness of the sponge sample after water absorption/the thickness of the sponge sample before water absorption) was calculated.
The number of the developing lines is more than one. Preferably, the number of development lines is two, preferably arranged in parallel, perpendicularly or diagonally crosswise, in which case the sponge can be more easily visualized and positioned with X-rays.
Preferably, the development lines are metallic barium wires or polymer wires impregnated with a radiopaque material, preferably polymer wires impregnated with barium sulfate (i.e. colloidal barium wires), more preferably the development lines are colloidal barium wires. The development line does not influence the absorption characteristic of the sponge body, and simultaneously ensures that the development line can be detected by an in-vitro X-ray machine, and sponge blocks which are missed in a body cavity can be conveniently found. Preferably, the color of the development line is blue, and the color of the development line is different from the color of blood and is not easily covered by red, so that medical personnel can be reminded to take out the sponge in time.
Preferably, the length of each development line is greater than 1/2 of the smallest side length of the sponge body. If the length of the development line is shorter than 1/2, which is the smallest side length of the sponge body, the development line is too short to be easily detected by an external X-ray machine.
Preferably, the development line and/or the traction tape are fixed to the sponge body by sewing or adhesion. For example, a developing wire or a pulling tape is sewn to at least one position of the sponge body, optionally passing through the center portion of the sponge body at least once. As another example, the development line may be any long and narrow radiopaque line that can be adhered to the surface of the sponge body by softening or partial melting.
Preferably, the sponge body is elongated. The size of the sponge body can be designed according to actual conditions. For example, the sponge body has a length of 8 to 15cm, a width of 2 to 5cm and a thickness of 1 to 3cm before absorbing liquid.
Preferably, the length of the traction belt exposed from one end of the sponge body is 3 to 10cm, the width of the traction belt is 1 to 2cm, and the thickness of the traction belt is 0.3 to 0.8 cm. When the length of the traction belt exposed from one end of the sponge body is shorter than 3cm, the sponge body is inconvenient to pull and is easy to slip; when the length of the traction belt exposed from one end of the sponge body exceeds 10cm, the length of the traction belt is too long, and the sponge body is not convenient to pull out quickly. Likewise, setting the width and thickness of the traction belt to 1 to 2cm and 0.3 to 0.8cm, respectively, facilitates the convenient traction of the sponge body while ensuring that it is not easy to slip.
Preferably, the traction tape is a metallic barium wire or a polymer wire impregnated with a radiopaque material, preferably a polymer wire impregnated with barium sulfate (i.e. a colloidal barium wire). More preferably, the traction belt is a colloidal barium wire. The traction belt does not influence the absorption characteristic of the sponge body, and simultaneously ensures that the traction belt can be detected by an in-vitro X-ray machine, and sponge blocks which are missed in a body cavity can be conveniently found. Preferably, the color of traction area is blue, and traction area color is different from the blood colour and is difficult for being covered by red, is convenient for remind medical personnel in time to take out the sponge.
The preparation method of the sponge for the laparoscopic/robotic surgery comprises the following steps: providing a mould and preparing a sponge body; the developing lines and/or the traction bands are fixed on the sponge body by sewing or bonding.
The sponge for the laparoscopic/robotic surgery and the preparation method thereof have the following technical effects: the sponge body is soft in material and excellent in absorption performance, and is favorable for tissue protection, operative field exposure and compression hemostasis. Due to the developing lines, the sponge device can be developed under X-rays so as to be convenient to find. Due to the provision of the pull tape, the mobile sponge device can be conveniently manipulated, for example in the abdominal cavity or removed, for example through a laparoscopic puncture. Accordingly, the sponge device of the present application is particularly suited for use in laparoscopic/robotic surgery.

Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. Wherein the same or similar parts are provided with the same reference numerals.
Example 1
In this example, a sponge for laparoscopic/robotic surgery was prepared as follows: providing a mould, and compressing to prepare a PU sponge body; and fixing the colloidal barium silk and the traction belt on the PU sponge by an adhesion method.
In the present embodiment, the sponge for laparoscopic/robotic surgery is shown in fig. 1, and includes a sponge body 1, a developing line 2, and a traction band 3. The development line 2 is fixed inside the sponge body 1 by adhesion for X-ray development. The traction belt 3 is led out from one end of the sponge body 1 and used for traction and moving the sponge body 1, so that the movable sponge device can be conveniently operated in the abdominal cavity or taken out through a puncture hole of the laparoscope.
In this embodiment, the sponge body 1 is made of Polyurethane (PU). The water absorption thickness expansion rate of the sponge body was measured to be 5 times according to the water absorption thickness expansion rate measurement method described above. In the present embodiment, the length of the developing line 2 is 1.5cm, which is 1/2 of the minimum side length of the sponge body 1.
The traction belt 3 is a colloid barium silk thread which does not affect the absorption characteristic of the sponge body, and simultaneously ensures that the sponge block missed in the body cavity can be detected by an in-vitro X-ray machine and conveniently found. The color of traction belt 3 is blue, and the traction belt color is different from the blood color and is not easily covered by red, so that medical personnel can be reminded to take out the sponge in time. The length of the traction belt 3 exposed from one end of the sponge body 1 is about 5 cm.
Example 2
A sponge for laparoscopic/robotic surgery in example 2 was prepared in the same manner as in example 1 except that: polyvinyl alcohol (PVF) is used as a material of the sponge body 1 instead of Polyurethane (PU).
The water absorption thickness swelling ratio of example 2 was measured in the same manner as in example 1, and the result showed that the water absorption thickness swelling ratio of example 2 was 3 times.
Further, the sponge of example 1 using Polyurethane (PU) is more flexible (favorable for tissue protection) and less likely to be hardened, compared to example 2 using polyvinyl alcohol (PVF).
Example 3
A sponge for laparoscopic/robotic surgery in example 3 was prepared in the same manner as in example 1 except that: the sponge body 1 contains hemostatic (one or more of thrombin, prothrombin, fibrinogen, calcium chloride, calcium alginate, and animal collagen).
Compared with example 1, the hemostasis time of example 3 is shortened from 5 minutes to 1 minute, and the hemostasis effect is better.
Example 4
A sponge for laparoscopic/robotic surgery in example 4 was prepared in the same manner as in example 1 except that: the sponge body 4 contains an antimicrobial agent (one or more of sulfadiazine, triclosan, mupirocin).
Compared with the embodiment 1, the sponge of the embodiment 4 can well inhibit the growth of microorganisms and prevent bacterial infection in the operation process while playing the roles of tissue protection, operation field exposure and compression hemostasis.
Example 5
A sponge for laparoscopic/robotic surgery in example 5 was prepared in the same manner as in example 1 except that: the length of the development line 2 is 1cm, 1/3 which is the smallest side length of the sponge body 1.
The development line of example 5 was shorter and the sponge body 1 was less noticeable under X-ray irradiation than in example 1.
Example 6
A sponge for laparoscopic/robotic surgery in example 6 was prepared in the same manner as in example 1 except that: the length of the traction belt 3 exposed from one end of the sponge body 1 is about 1 cm.
Compared with example 1, the traction belt 3 of example 6 is too short to pull the sponge body 1 and is liable to slip.
Example 7
A sponge for laparoscopic/robotic surgery in example 7 was prepared in the same manner as in example 1 except that: the length of the traction belt 3 exposed from one end of the sponge body 1 is about 15 cm.
Compared to example 1, the traction belt 3 of example 7 is too long to facilitate quick pulling out of the sponge body 1.
As shown in FIG. 2, in a subtractive laparoscopic colon cancer surgery, the sponge according to an embodiment of the present invention can absorb blood and hemostasis by compression well at and near the surgical site, sufficiently protect surrounding tissues, and sufficiently expose the surgical field by blocking the small intestine.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts.
