Customizing Surgical Dissectors Using 3D Printing
This patent describes a surgical tool's working tip, called an end effector, which has two jaws whose gripping features can be custom-made using 3D printing for specific surgical needs.
Original patent title: “Surgical dissectors and manufacturing techniques”
This patent describes a surgical tool's working tip, called an end effector, which has two jaws whose gripping features can be custom-made using 3D printing for specific surgical needs. Granted to Ethicon in 2021 with 29 claims and 354 forward citations, and it is expected to expire in 2038.
Coverage
What does this patent actually cover?
The patent describes a surgical end effector, which is the working tip of a surgical instrument, featuring two jaw members that can open and close. The key innovation is that at least one specific 'feature' on these jaws can be chosen by a user and created using an 'additive manufacturing process' (ClaimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → 1). This means a surgeon or manufacturer can design unique patterns or shapes on the gripping surfaces of the jaws, such as a 'tooth' on one jaw and a complementary 'void' on the other (Claim 4), or even use different materials for different features (ClaimsclaimsThe numbered statements at the end of a patent that legally define what the inventor owns.Read more → 5, 6). For example, a surgeon could specify a unique symmetrical pattern of protrusions on one jaw and a complementary pattern on the other for a specialized tissue grip (Claim 7), then have it 3D printed.
The gap
What does this patent NOT cover?
- Surgical instruments that do not include two jaw members that are independently movable relative to each other (ClaimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → 1).
- End effectors where neither the first feature of the first jaw member nor the first feature of the second jaw member is selected by a user in an additive manufacturing process (ClaimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → 1).
- Manufacturing methods for the jaw features that are not additive manufacturing, such as traditional molding or machining (ClaimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → 1).
- Surgical tools where the jaw members do not pivot about a joint between an open and closed configuration (ClaimclaimA numbered sentence at the end of a patent that legally defines what the inventor owns. The most important section.Read more → 1).
- Dissectors where the features on the jaws are fixed and cannot be customized or varied by a user during manufacturing.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
The noveltynoveltyThe requirement that an invention be different from anything publicly known before its priority date.Read more → lies in integrating user-selected, additive manufacturing (like 3D printing) directly into the design and production of specific functional features on surgical jaw members. This allows for on-demand, customized surgical implements rather than relying solely on mass-produced, generic tool designs.

Market impact
This patent contributes to the growing trend of personalized medicine by enabling the creation of highly specialized surgical tools. It could lead to more efficient surgeries and better patient outcomes by providing instruments precisely adapted to individual needs, rather than requiring surgeons to adapt generic tools. It also underscores the increasing adoption of additive manufacturing in the medical device industry, allowing for rapid prototyping and production of complex, customized geometries.
Claim 1 — Plain English
What this patent covers
The patent describes a surgical end effector, which is the working tip of a surgical instrument, featuring two jaw members that can open and close. The key innovation is that at least one specific 'feature' on these jaws can be chosen by a user and created using an 'additive manufacturing process' (Claim 1).

The clever bit
The novelty lies in integrating user-selected, additive manufacturing (like 3D printing) directly into the design and production of specific functional features on surgical jaw members.
